egg incubation
Let an agent explain egg incubation, relay natural and artificial methods, parameters, candling and history from poultry science and conservation sources, advise on hygiene, and distinguish egg incubation from brooding chicks after hatching, incubation periods of disease, reptile temperature-dependent sex determination and egg storage.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain egg incubation, relay natural and artificial methods, parameters, candling and history from poultry science and conservation sources, advise on hygiene, and distinguish egg incubation from brooding chicks after hatching, incubation periods of disease, reptile temperature-dependent sex determination and egg storage.
The process of keeping fertilised eggs at suitable temperature and humidity so embryos develop until hatching, done naturally by brooding birds and some reptiles, or through artificial incubation in incubators, used in poultry hatcheries, conservation breeding and backyard flocks, with chicken eggs typically needing about 21 days at around 37.5 degrees Celsius with regular turning and higher humidity before hatching; ancient Egyptian and Chinese egg ovens show artificial incubation has a long history. Handling eggs and chicks can spread Salmonella, so hands should be washed.
What it is for: Hatching eggs.
It can be explain natural and artificial methods; relay temperature, humidity and turning; describe candling; relay hygiene.
Distinguishing features
Temperature control
Humidity control
Egg turning
Species-specific periods
What it looks like
A hen sitting on a nest, or eggs in a temperature-controlled incubator.
Physical character
chicken incubation period: about 21 days
forced-air incubator temperature: about 37.5 degrees Celsius - chicken eggs
duck incubation period: about 28 days - most breeds
How it is recognised
Keeping eggs warm to develop embryos
Artificial incubation, natural incubation, hatching
Brooding keeps chicks warm after hatching; disease incubation is a different sense; reptile TSD concerns sex; egg storage prevents development
