Hatchability of the fertilized avian egg is impacted by factors which can be
categorized as being either genetic or environmental in nature. An elevated
incubation temperature, > 100 F reduces development time (time, days to hatch),
but increases embryonic mortality and lowers the numbers of fertile eggs that will
hatch....
The first decision to be made is whether to incubate eggs naturally or artificially. Natural incubation uses a broody hen to incubate eggs by sitting on them in a nest. Broody hens, when available, work best for small clutches of eggs.

We studied avian development in 49 species of temperate and 153 species of tropical New World passerine birds to determine how growth rates, and incubation and nestling periods, varied in relation to other life-history traits. We collected growth data and generated unbiased mass and tarsus growth rate estimates (mass n...

A genetic selection study to determine the effects on egg hatchability and subsequent chick performance of Japanese quail (Coturnix japonica) eggs incubated at 100 F dry bulb temperature (Control, Line C) when compared to other eggs incubated at 102 F (Selected, Line S) was conducted over 10 consecutive generations. Eggs...
