Avicolturists, people who raise birds for commercial sale, have not yet learned
how to simulate the natural incubation of parrot eggs in the wild. They continue
to look for better ways to increase egg production and to improve chick survival rates.
line When parrots incubate their eggs in the wild, the temperature and humidity of the nest are controlled naturally. Heat is transferred from the bird’s skin to the top portionof the eggshell, leaving the sides and bottom of the egg at a cooler temperature. Thistemperature gradient may be vital to successful hatching. Nest construction cancontribute to this temperature gradient Nests of loosely arranged sticks, rocks, or dirtare cooler in temperature at the bottom where the egg contacts the nesting material.
Such nests also act as humidity regulators by allowing rain to drain into the bottomsections of the nest so that the eggs are not in direct contact with the water. As thewater that collects in the bottom of the ne
