To ensure the good health of breeding Parakeets and their babies, a male and female pair should be unrelated, free of disease and birth defects, and at least 1 year old.
A cage for a pair of breeding Parakeets should be a minimum size of 20" x 20" x 20", and should contain a wooden nest box that is at least 12" x 12". Some Parakeet breeders place wooden inserts into the bottom of their nest boxes to prevent splay legs. Proper nesting material, such as pine shavings, should be provided.
Parakeets are hookbills, and as such, should be fed a varied diet consisting of seed, high quality pellets, and plenty of fresh fruits and vegetables. Breeding pairs should be provided with a cuttlebone and calcium supplement to ensure proper egg development and to help the hen recoup nutrients lost in the egg-making process.
Female Parakeets will lay their eggs relatively soon after mating. Like many other types of birds, it's not uncommon for Parakeets to lay one egg every other day until they have all been laid. There are usually between 4 and 8 eggs in each clutch, although this can vary.
On average, Parakeets incubate their eggs for between 17 and 20 days. This can vary by a couple of days in either direction, and is usually no cause for concern.
Hatchling Care and Weaning:
If the Parakeet babies are to be tamed as pets, many breeders will let the parents raise the chicks until they are weaned. During this time, they will handle the chicks now and then to get them used to human hands. Most baby Parakeets are weaned by the age of 6 weeks, and can then be removed from the parents and interacted with on an individual basis.
