Hatcher
A hatcher is a type of incubator used specifically for the final stage of incubation when eggs are set to hatch. Ensuring proper humidity and temperature during this stage is critical for successful chick hatching.
Ventilation in Incubation
Ventilation in incubation refers to the exchange of air in an incubator, which is necessary to provide fresh oxygen for the embryo and to remove waste gases like carbon dioxide. Proper ventilation is vital for embryo health.
Setter
A setter is a type of incubator that maintains fertile eggs in a controlled environment during the first stages of incubation. It is crucial in providing consistent temperature, humidity, and egg turning until transfer to a hatcher.
Incubation Temperature
Incubation Temperature is the specific range of temperature required to properly incubate eggs. For chicken eggs, this is typically between 99.5°F and 100.5°F (37.5°C - 38°C). Correct temperature is essential for normal embryo development.
Hatchability
Hatchability refers to the percentage of fertilized eggs that successfully hatch into chicks. High hatchability is an indicator of good flock sexual balance, proper egg handling, and effective incubation.
GQF (Georgia Quail Farm) Incubator
The GQF Incubator is a popular brand of commercial incubators known for reliability and uniformity in hatching eggs. They are used extensively in poultry science for research and production because they can accommodate various egg sizes and types.
Turning Eggs
Turning eggs is the process of rotating incubating eggs several times a day to prevent the yolk from sticking to the shell and to mimic the natural behavior of a brooding hen. This is essential for normal embryo development.
Embryonic Development
Embryonic Development refers to the process by which the avian embryo forms and grows inside the egg. It's crucial for understanding the stages of growth and ensuring proper incubation conditions are met.
Egg Storage
Egg Storage refers to the conditions under which fertile eggs are kept before incubation. Proper storage (cool temperatures, adequate humidity) ensures minimal loss of viability and maximizes the eggs' hatchability.
Pipping
Pipping is the process where a chick breaks the shell membrane and the eggshell in order to hatch. It is an important sign that hatching is imminent and that the chick has developed sufficiently to survive outside the egg.
Fertile Egg
A fertile egg contains a viable embryo that has the potential to develop into a chick. Fertility is critical for hatchability and is determined by the presence of a rooster in the flock and proper hen management.
Candling
Candling is a technique used to observe the growth and development of an embryo inside an egg. It involves shining a light through the egg to view its contents and is important for determining egg fertility and normal development.
Incubation Period
The incubation period is the time required for an egg to develop and hatch into a chick. For chickens, it typically lasts 21 days and is influenced by temperature, humidity, and egg turning.
Brooding
Brooding is the process of providing the necessary warmth and care to young chicks until they can maintain their body temperature and adequately adapt to their environment. It is vital for early chick survival and growth.
Incubation Humidity
Incubation Humidity is the amount of moisture in the air within an incubator. The ideal range for chicken egg incubation is 45-55% during the early stages and up to 65% during hatching. Proper humidity prevents dehydration and aids in chick hatching.
