Are All Hatcheries Expected to
Perform the Same?
In Reality Can All Hatcheries
Perform the Same?
What Is Hatchery Performance
Based On?
How Is Your Hatchery Performing?
Considering the Number One Goal
of Any Successful Hatchery
--------Being-------Good Quality Chicks Produced at
the Least Cost
Is This Still Achievable
With the Old Multi Stage
Incubation Concept?
One Important Fact to Establish
and Consider
------is-----All Multi Stage Hatcheries I Visit
Are Not the Same (Equal)
There Are Many Things to Consider
But
Simply Only Two Basic Categories
Standard
OR
Non - Standard
What Makes a Standard Hatchery?
Simply Must Have All of the Basics!
• Good Stable Reliable Electricity
• Good Quality Water That Meets the Correct
Criteria
• Good Clean and Dry Compressed Air That Meets
the Correct Criteria
• Good Ventilation That Properly Supports the
Machines and Embryos
• Good Egg Pack That Meets the Correct Criteria
• Along With Good Management and Maintenance
Non - Standard Hatcheries
------Requires-----Non - Standard Practices
Manipulation
Compromise
------Most Often Causing-----Misunderstanding
Confusion
Inferior Results
To Put This Into Perspective
• What You Do?
• What You Have?
• What You Do With What You Have?
• What You Should Do?
--------------------------------------------------------
Determines Your Success or Failure!!!
Multi Stage Incubation Four Things To Consider
1. Recommendation (Specifications - Type, Adjustments and Etc.)
2. Procedures (Egg Handling, Set, Transfer, Pull, Process & Delivery
3. Principle
•
•
•
•
•
Embryo development requires O2 and creates CO2
As air moves from the old to the fresh eggs it picks up CO2 and heat
Heat and CO2 is supplied to freshly set eggs, cooling conditions and extra oxygen
for the older eggs in the 5th and 6th rack positions
Sometime, between 18 and 18½ days of incubation eggs are transferred to Hatcher
181/2 days - 12 hour 6th position
•
18 days - 24 hour 6th position
4. Concept
•
•
•
•
Heat (Majority Supplied by Embryonic Development in the 5th and 6th Positions)
Humidity (Two Purposes: 1. Humidification and 2. Cooling)
Airflow (Forced Air - Laminar - Negative Pressure)
Turning (Two Purposes: 1. Early Embryonic Development and 2. Airflow Balance

Today’s Successful Hatchery
The Hatcheries That I Deal With That Are Achieving
Their Expectation Are Following the
Recommendations and Guidelines Set Forward in the
Manuals Supplied By The Manufacturer as Well as
Applying and Adhering to the Basics and Details in
Regard to the Advanced Genetics of Today’s Modern
Breeds and the Incubation Equipment in Use
Recommendations, Procedures, Principles and
Concept
In Today’s Poultry Industry Many
Things Have Been Done in Most Areas
to Accommodate the High Yield Meat
Type Bird Being Produced
• Feed and Feed Mill
• Breeder - Feed, Housing and Management
• Grow Out - Feed, Housing and Management
• Processing - Basically Anything Wanted
• Sales and Marketing - Dictates Production
TEAMWORK - COMMUNICATION - In the Hatchery as Well as Total
Feedmill - Breeder - Hatchery - Broiler - Processing - Sales
• Hatchery Seem to Have Been Left Out of the Update
The High Yield Advanced Genetics of
Today’s Breeds At Best Presents More
Challenges Than Ever In Regard to the
Basics and Details of Proper Incubation. The
Advanced Genetics With Less Consideration
To Hatching and Emphasis Primarily on
Growth and White Meat Yield Requires
More Attention Than Ever Before.
However very good and comparable results
in regard to hatching and chick quality are
being consistently achieved with these breeds
(Even In Some Very Old Facilities).
In Order to Accomplish Our Goal
at the Hatchery of Good Quality
Chicks at Least Cost
----------------------------Must Start With the Basics
-----------------------------Without the Basics We Are
Defeated or To Say the Least
Handicapped From the Start
Four Basic Inputs That Must Be
Provided to the Machines
(Influences Outside the Machines)
•Proper Electricity
•Proper Water (Quality,Volume and Pressure)
•Proper Compressed Air
•Ventilation
Also Proper Egg Pack - Very Important Input
Proper Design and Layout is a Must
Proper Electricity
Proper and stable electricity must be supplied
due to the controls being microprocessors and
the components in the control box being solid
state. Improper electricity is a major
contributor to improper calibration plus the
longevity of the control system will be
negatively affected. E/M Controls are less
sensitive but can be negatively affected due to
control component wear and tear. Heat rod
amperage can also be affected.
Proper Water
Proper water must be supplied in regard to
quality, volume and pressure due to its
influence of cooling and moisture lost in the
eggs. Incorrect water affects evenness of the
temperatures in the incubator, higher
temperature at the top and lower at the
bottom. Although the Jamesway Multi Stage
Incubation System is by definition air- cooled
the spray also contributes. In reality 70% of
the cooling is from the air intake and 30%
from the proper spray.
Proper Compressed Air
Proper compressed air must be supplied in
regard to cleanliness and dryness due to each
incubator rack turn with its individual air
cylinder. Oil and water from the air compressor
must be properly handled and eliminated to
prevent premature air cylinder failure.
------------------------------------------------------Proper air pressure @ 65 PSI minimum at the
buggies must supplied to allow for proper
turning. Improper lines can also create problems.
Proper Ventilation
The sole purpose and definition of proper ventilation is
to replace stale air with fresh air, which is needed by
the developing embryos in their varying stages of
embryonic development. Multi Stage incubation works
on average (average temperature, humidity and
damper operating range, O2 – CO2 balance) and is
non-specific to any particular stage of embryonic
development but maintains a proper average for all.
Proper ventilation is a basic input in Multi Stage
incubation that must be properly sized, designed,
controlled, installed and maintained to allow for correct
embryonic development as well as proper machine
performance and efficiency.
Factors to Consider:
EGGS FROM FARM TO INCUBATOR
•
•
•
•
•
•
Egg Pack Uniformity
Egg Handling on the Farm
Farm Egg Storage
Hatching Egg Transportation
Hatchery Egg Storage
Egg Storage to the Incubator
EGG PACK UNIFORMITY
As Observed Now Commonly Accepted
As Normal in Today’s Industry
• SIZE - Influences Airflow and Varying
Embryonic Heat Based on Chick and Fertility
• SHAPE - Same plus Impaired Chick Quality
• SHELL QUALITY - Influences Moisture
Lost and More Susceptible to Contamination
• CLEANLINESS - Garbage in = Garbage Out
In Today’s Industry a Proper Understanding
and Application of the Basics Must Be
Considered and Applied in Regard to
Embryology and the Incubation Equipment in
Use
- Considering The Four Basic Requirements for Incubation
(Inside the Machines)
a. Heat
b.Humidity
c.Airflow
d. Turning
A. Three Controlled Factors in an
Incubation System
a. Temperature
b. Humidity
c. Damper
B. One Established Factor
a. Airflow
C. One Programmed Factor
a. Turning
In General the Four Basic Requirements To
Achieve Correct Incubation
• Heat - Determines Air Temperature That Dictates
Speed of Embryonic Development
• Humidity - Controls Moisture Lost and Afford Some
of the Cooling
• Air Flow - Generated by the Fans Creating the
Correct Air Movement Through the Egg Pack
(To Obtain, Maintain and Distribute the Correct Air
Temperature to Achieve and Control Constant Embryo
Temperature)
• Turning - Keep Embryo in the Correct Position in the
Early Stages of Embryonic Development to Avoid
Sticking to the Sides as it Develops
ALSO Very Important is the
• Damper - Controls O2 and CO2
Four Basic Requirements That Achieve the Correct
Averages for Jamesway Multi Stage Incubation
• Heat - Air Temperature That Determines Speed of Embryo Development Damper is the Key - Controlled By The Temperature (Heat) Set Point and
Controls O2 and CO2 Balance As Well As Negative and Positive
Incubator Pressure Note: Heat Set Point is the Only Controlled Temperature Lowering the Heat Set Point Will Raise the Egg Pack Temperature - Damper
Open (70% of the Cooling is Attributed to the Damper - Air Cooled)
• Humidity - Supplied by Four Spray Nozzles That Controls Moisture Lost
and Afford Approximately One Third of the Cooling in Jamesway Multi
Stage (30%Cooling Attributed to Spray)
• Air Flow - Generated by Six Fans Creating the Correct Air Movement
Through the Egg Pack (1. Forced Air - Positive, 2. Laminar - Smooth
Steady and 3. Negative - Draws Through Egg Pack)
• Turning - Compressed Air Supplies Air Pressure to Individual Rack Air
Cylinder Turning Egg @ 45 Degree
1. Early Embryonic Development
2. Air Flow Balance
Two Types of Incubation in Today’s Industry
1. Multi Stage Incubation
a. Still by far the most common (varying stages of
embryonic development in each incubator) = 80%
b. One way system to achieve averages for all
c. Interdependent (Each group of embryos supports and are
dependant on the other)
2. Single Stage Incubation = 15%
a. All in - All out
b. Flexibility
c. Biosecurity
STATEMENT: Industry Trend Is Toward Single Stage

With the Challenges of Today’s Industry
and the Embryo From the Genetically
High Yield Breeds Single Stage
Incubation is Fast Becoming the System
of Chose Over Multi Stage Incubation
Due Primarily to the Single Stage System
Can Be Profiled to Meet the Specific
Needs of the Embryos Whereas Multi
Stage Incubation Operates on Averages
If You Was Building a New Hatchery Which
Incubation Would You Choose??
General Statement of Hatchery
Managers with Experience in Both
Multi Stage and Single Incubation
Systems is:
Single Stage Incubation!!!
It is Easier!!!
WHY???
Multi Stage -vs.- Single Stage
Multi Stage Incubation
• Managing the Needs of
Each of the Varying
Stages of Embryonic
Development
• Understanding Each
Stage Has Its Specific
Requirement in Relation
to Heat,
Humidity,Airflow and
Turning
Single Stage Incubation
• Manages the Needs of Each
of the Varying Stages of
Embryonic Development
• With the Understanding
Each Stage Has Its Specific
Requirement in Relation to
Heat, Humidity,Airflow
and Turning
• THE PROFILE IS THE KEY!!!
Multi Stage -vs.- Single Stage
Multi Stage Incubation
• Managing a Multi - Stage
Hatchery in Today’s Industry is
a Skill That Requires Attention
Be Paid to Each of the Details
That Affects Embryonic
Development as Well as the
Performance and Efficiency of
the Machines All Considered as
They Influence Our Number
One Goal
• (Good Quality At Least Cost)
Single Stage Incubation
• Single - Stage Incubation in
Today’s Industry
Incorporates the Attention to
Each of the Details That
Affects Embryonic
Development as Well as the
Quality of the Chick Hatched
THE PROFILE IS THE KEY!!!
A Very Important Difference That Is
More and More Coming To The
Forefront In Regard to Single Stage
verses Multi Stage
----IS---A. Multi Stage Incubation Operates
on Averages
B. Single Stage Incubation Operates
On Specifics
Today’s Embryos Seem to be
More Susceptible and Less
Viable in Regard to Incubation
Simply Will Not Take As Much
Temperatures Variations
Single Stage Incubation Can
Better Meet the Specific Needs
Benefits That Can Be
Attributed To Single Stage

BIO-SECURITY
• Term that the poultry industry is using
more and more frequently. As production
of poultry becomes more intensive, and
genetic selection produces a chicken that
is faster growing but possibly more
susceptible to disease, all aspects of the
production process have to establish
procedures to maximize the levels of
sanitation and hygiene.
Bio Security
Warm temperatures and high humidity levels required
for incubation also provides an ideal climate for
bacteria growth. The Single Stage machines can be
thoroughly cleaned and sanitized after each cycle of
eggs without any disruption to the incubation process.
This high level of cleanliness not only improves chick
quality but also reduces field mortality. As well any
contamination that does occur is contained within the
batch of eggs inside the machine and can be addressed
during or after the incubator is emptied.
FLEXIBILITY
• Eggs can be loaded into the setter upon
arrival to the hatchery. (Incubator Can Be Used as
Egg Storage and Proper Pre - Warming all as per Profile)
• Not locked into twice per week setting as
with multi-stage.
• Adjust temperature and humidity
according to breed, age of eggs, and/or
eggs size to maximize hatch results.
• Programmable profiles and alarms
FLEXIBILITY

Specifics
With Your Understanding and Knowing the Variables
or Factors in Regard to Your Particular Egg Pack You
Can Specifically Profile the Single Stage Incubation
System to Meet the Specific Needs and Requirements
of Each Group of Eggs You Put Into Incubation
Example:
1.Young Flocks (Small Eggs- Less Embryonic Heat ) = 20%
2. Old Flocks (Large Eggs - Low Fertility) = 20%
3. Prime Flocks (Average Size Eggs - High Fertility) = 60%

Your Jamesway Hatcheries
----- ARE ----As Of Now All Multi Stage So
Lets Now Focus On
------------The Jamesway Multi Stage
Incubation System
What Can Be Done To Improve !!!
I Observed Some Improvements (Example:
Water Pressure) in the Hatcheries From
Previous Visit and I Sincerely Thank
You All For The Efforts Put Forth
---------------But-----------------As In Any Hatchery There Are Still
Opportunities To Improve (Even in Many Areas
Previously Discussed and Reported)
Your Results As Observed, Reported and
Discussed Still Reveals Many Areas of
Opportunities
Many Asked: “What has been done to improve
Multi Stage Incubation??”
The fact is:
Nothing in regard to Concept. If you will follow
and apply the basics and details correctly Multi
Stage Incubation even with today’s advanced
genetic embryos will be quite successful, very
efficient in regard to results and cost.
-------------------------BUT-----------------------As I observe Multi Stage Incubation worldwide this
simply is not being done therefore alternative
concepts are being advocated.
The Major Concern
Impaired Hatch and Chick Quality
Objective of this Visit
To Again Identify the Causes and Help
Set Up a Plan to Alleviate
The Number One Concern At Hatcheries
I Visit Is Simply Incorrect Incubation
Temperature Related To The Four
Requirements of Incubation
1. Heat
2. Humidity
3. Airflow
4. Turning
The Jamesway Multi Stage Concept
The Causes of the Incorrect
Incubation Temperatures
Are:
1. Improper Procedures
2. Improper Water
3. Improper Ventilation
4. Maintenance Issues
Note: All Inclusive - What Else Is It???
THE FOUR WORDS TO CONSIDER
THAT DETERMINE PROPER
INCUBATION
• RECOMMENDATION - Requirement - Specs
(Supplied By Manufacturer)
• PROCEDURE - Method Of Doing Things
(Directly Under Your Control)
• PRINCIPLE - Method Of Operation
(Established By The Manufacturer’s Design)
• CONCEPT - What, Why and How It Works
(Created By The Equipment Design)
Recommendations
• Provided by the Manufacturer

Correct To Maintain Its Quality and Viability
The Fertile Egg
• 22 Days Incubation - 1st Day Occurs in Hen
• Hen @ 104.5F - Cuticle Applied For Protection
• Laid By Hen Into A Clean Nest
• Collected - Graded - Put on the Egg Flat
• Cooler @Farm 65 - 68F and 75%RH
• Remains in Farm Cooler 24 - 48 Hours - Incubation Stops
When Temperature Inside Egg Cools to 72F - Normally in
Farm Racks 12 - 24 Hours
• Transported to Hatchery in Refrigerated Truck @ 65 -68F
• Hatchery Egg Room @ 65 - 68F - Prepared for Set
• Egg Set 3 - 5 Days From Time Of Lay
Why Cool the Eggs ???
(Two Main Purposes)
1. Suspends Embryonic Development
(All Embryos Put Into Incubation At Same Stage)
--------------------------------------------------------------
2. Thickens The Thick Albumen
(Utilized By Embryo During Development)

and Damper Start Operating - 4 Hours the Air Temperature at Position 1
(freshly set) Reaches 100.3F - 8,10 to 12 Hours the Temperature Inside the
Eggs at #1 Position Reaches 100.3F - Then the 6th Position is Transferred Finished with Embryonic Heat
•----------------------------------------------------------------------------------------------• Thurs. - Fri.: The Embryos That Assume the Sixth are 17 Days Old @
100.0F = .4 BTU Heat Production - Takes 1 Hr. To Reach 98.8F and
Damper Start Operating - 6 Hours the Air Temperature at Position 1
(freshly set) Reaches 100.3F - 20,22 to 24 Hours the Temperature Inside
the Eggs at #1 Position Reaches 100.3F - Then the 6th Position is
Transferred - Finished with Embryonic Heat
Pull Times
• Process/pull time should be established by

Heat and CO2 Required at the Start of Embryonic
Development - Where Does it Come From?
1. Heat - Mechanical and Embryos
2. CO2 - Developing Embryos and Control of Fresh and
Exhaust Air (Damper)
Embryonic Development
is a progressive change in the molecular
structure (Metabolism - Growth).
The Natural By-Product of Embryonic
Development is Heat and CO2

Embryonic Development
in the incubators and hatchers requires oxygen.
Where does this oxygen come from?
Normally, the oxygen is made available
through the fresh air introduced by the HVAC
(Heating, Ventilation and Air Conditioning)
systems and allowed in the incubator through
the intake air damper.
Jamesway Set Point Temperature is Supplied to the Oldest
Embryos and is Established by the Mixing of the Fresh
Intake Air with the Air Exiting the Egg Mass into the
Mixing Chamber, Then Through the Fans, Over the Top of
the Incubator Rack to the Fifth or Sixth Position.

The Fertile Egg
contains a live, very delicate
embryo.
Heat and CO2 Required at the
Start of Embryonic
Development
----------------------------Cooling and Oxygen Required
at the Later Stage of Embryonic
Development
As Embryonic Development (Heat) Starts and
Progresses in the Incubator and Finalizes in the
Hatchers the Embryo’s Requirement for the Proper
Heat, Air and Gas Exchange is Ever Present
---------------------------------------If Not Correct Throughout the Entire Incubation
Cycle Will Result in Irreversible Embryonic Damage
as Well as Inefficient Machine Performance
----------------------------------------------------An Insured Means of Provision is Required
That Means is Proper Ventilation
Ventilation Means Introduction of Fresh Air
(the replacement of stale air with fresh air)
All Incubators Need Fresh Outside Air
(due to embryonic development inside)
Air only machines (as Jamesway Multi Stage) uses fresh
air for cooling and carbon dioxide control.
Heating and/or cooling is required depending on the
stage of embryonic development.
Air and water machines (as Jamesway Single Stage) use a
combination of air and water cooling/heating.
Proper Hatchery Ventilation System
Ventilation System Must Be:
1. Properly Sized
2. Properly Designed
3. Properly Controlled
4. Properly Installed
5. Properly Maintained
For Each Individual Hatchery to Supply the Correct
Requirements of Temperature, Humidity and Pressure Needed
for the Embryonic Development and the Performance and
Efficiency of the Machines
How Ventilation Will Affects the Machines
1. Incorrect Room Temperature - Creates Incorrect
Air Temperature Mixture Coming Through the Fans
Low = Damper Close (Winter) - High = Damper Open (Summer)
2. Incorrect Room Humidity
High = Damper Open - Spray Does Not Come On Inside Incubator
90% Air and 10% Spray Ratio Inside Incubator (Summer)
Low = Damper Closes Spray On Too Much Inside Incubator
30% Air and 70% Spray Ratio Inside Incubator (Winter)
-------- Normally 70% Cooling = Air and 30% = Spray --------3. Room Pressure - Negative = Blocks Intake Air ------------------- Too
Positive = Deludes Negative Incubator Pressure
Ventilation Effects in the
Incubator
• Damper Performance
• Machine Efficiency
and Stability
• Temperature and
Humidity
• Chick Quality
Incubator Set Points
• Temperature 98.8 Super J ( Big J 99.0)
• Humidity 86.0
Hatcher Set Points
• Temperature 98.5 Super J (Big 98.8)
• Humidity 86.0
Statement of Observation:
• Anytime You Adjust The Set Point in a
Jamesway Machine It Is To Compensate For
Other Concerns That Should Be Addressed
Altering Set Points
• Jamesway - Air Cooled - Heat Set Point Controls Damper (Cool)
•Other Manufacturer - Water Cooled- Cooling Set Point Controls
•Lowering Temperature Set Point - 98.8F to 98.6F - Senses Too Hot -Opens
Damper - More Air Cooling Required - Heat Not On - Negative Pressure Drops
- Air Does Not Go Through Egg Pack Properly = Overheating Passed Oldest
Embryos
•Raising Temperature Set Point - 98.8F to 99F - Senses Too Cool - Damper
Closes More - Less Air Cooling Required - Heat Is On More - Oxygen and
Cooling Reduced to Older Embryos - Overheating Throughout Egg Pack
•Lowering Humidity Set Point - Opens Damper - Reduces Cooling Attributed to
Spray - Raises Mixed Air Temperature
•Raising Humidity Set Point - Closes Damper - Increases Cooling Attributed to
Spray - Lower Mixed Air Temperature
Jamesway Multi Stage - Damper
Performance is the Key (Air Cooled)
MUST Understand the Importance and
Achieve the Proper Damper Performance
1. PT-100 - Normal Operating Range of
1-1/4 to 1-3/4 inches with 1-1/2 inches Average
Position @ 250 CFM Air Intake
2. E/M - Normal Operating Range of
1 to 1-1/2 inches with 1-1/4 inches Average
Position @ 250 CFM Air Intake
The Multi Stage Damper
• Multi Stage = Air Cooled
• Damper is Controlled by Heat Set Point
• Damper Controls Temperature and
Incubator Pressures
• Damper Regulates O2 and CO2
• Damper = Average Needs of ALL Varying
Stages of Embryonic Development
• Damper is the Key to Correct Multi Stage
Incubation
General Rule of Thumb in Regard
to Proper Incubation
• 36 Hours Before Pull Hear 1st Chick
• 30 Hours Before Pull 1st Chick Out
• 24 Hours Before Pull 5 - 10% Hatched
• 12 Hours Before Pull 50 - 60% Hatched
• 4 - 6 Hours Before Pull Last Chick Out
• At Pull 5 - 10% Still Damp on the Neck
