A range of temperatures where embryonic development is stopped, but the embryo remains alive. An example is storing eggs in the refrigerator for a long time.

The ideal relative humidity for the first 18 days of incubation.

A device used to measure humidity levels. Some types are built into incubators.

The process of rotating eggs during incubation to ensure even development of the embryo and prevent the chick from sticking to the shell.

A type of incubator where air is circulated, resulting in a more uniform temperature.

The opening on the incubator where air can leave

A key component of a forced air incubator that ensures efficient air circulation.

A specific area in an incubator where hatching takes place.

The period where a bird sits on its eggs to keep them warm, allowing the embryo to develop.

The process where a chick emerges from its eggshell after development.

The ability of an egg to produce a chick.

The percentage of fertilized eggs that actually hatch.

The age of the flock and roosters affects the number of fertile eggs produced.

Maintaining high fertility levels in breeder flocks requires ensuring they are at the optimal age, typically between 40 to 50 weeks for hens and 30-35 weeks for roosters.

Storing eggs in a cool, humid environment (13-18°C, 75% RH) with the small end down helps maintain hatchability.

Hatchability decreases rapidly after 7 days of storage, so it's crucial to incubate within this timeframe.

A method of measuring relative humidity using a thermometer with a wet bulb.

The amount of surface area of water in an incubator's water tray and the flow of fresh air into the incubator directly impact humidity levels.

The expansion of the air cell inside an egg as incubation progresses, observed by candling.

The percentage of weight loss an egg experiences from laying to hatching should ideally be around 12.6%.

The process of providing fresh oxygenated air to an incubator or hatcher, essential for embryo respiration.

The allantois, a respiratory organ that develops inside the egg, takes over as the primary respiratory organ after the 4th or 5th day of development.

The process of rotating eggs in an incubator to prevent the embryo from sticking to the shell and ensure proper circulatory development.

The percentage of fertile eggs out of all incubated eggs.
