It takes between 17 and 20 days for parakeet eggs to hatch. The female parakeet lays an egg approximately every other day until her entire clutch has been laid. A clutch is typically four to six eggs, but it is not unusual for the number to fall outside that range.Know More
The eggs will hatch every other day in the order they were laid, though the first two may hatch on the same day if the mother waited before starting to brood. Newborn chicks have no feathers. They first develop down and then pin feathers, which eventually open with maturity.
