The hen and cock should be kept in the cage together. A hen can lay up to six or seven egges. She lays one every day until she is done. The hen will sit on her eggs for 18 days before they hatch. The babies are born blind and without feathers.
Parakeets look very weird when they are just born.
For about six weeks, the father parakeet will feed the mother parakeet while she keeps the babies warm. The mother parakeets then feeds the babies. After 17 days, downy feathers start to grow on the babies. When they are 23 days old, the baby parakeets grow pinfeathers that cover head. At 27 days old, the parakeets look almost fully grown.
