Incubation Process of a Chicken
By:Erin Webb
Preparation Stage Chick incubation process is 21 days Gather fertilized eggs 2 – 3 days in
advance Set up incubator to maintain
temperature of 99.5°F Add water for humidifying purposes Mark eggs
From Egg to Chick:Incubation Procedures1. Obtaining and caring of eggs
Gather fertilized eggs from a farmer
Eggs should be stored at a temperature of around 50°F until incubation begins
Eggs should not be more than 5-7 days old
2. Preparing the incubator
Incubator should be out of direct sunlight in a room temperature of 70-75°F
Maintain incubator temperature of 99-103°F
For humidifying purposes, add water to bottom of incubator
3. Preparing the eggs for incubation
To ensure proper turning, mark all eggs on one side with an “x”, the other side with an “o”
Demonstrating the marking process
During incubation... Turn eggs 2-3 times per day to prevent
embryo from sticking to the shell membrane; until the 17th day
Candling the eggs:Allows you to see clearly the developing embryo stages and dispose of the infertile eggs and/or dead embryos
Examples of Bad Eggs
Examples of Good Eggs
Disposing of non-developing eggs
Embryonic Development Stages
Final Stages of Incubation
After the 17th day... Eggs should not be turned Incubator should not be opened unless
it is necessary to add water All chicks which are going to hatch
should be out of their shells by the 21st day
Reasons for Poor Hatches Infertile eggs Eggs too old when set Parent stock weak, unhealthy, or fed a nutritionally
deficient diet Improper care of eggs prior to incubation Shell contamination Eggs not turned often enough Temperatures too high, too low, or too variable during
incubation Too little humidity in the incubator or occasionally too
much Improper ventilation Oxygen starvation
