I'm reposting this for thunderbird, from another topic area.
I have a male and a female parakeet. the female has laid 4 eggs. One of the eggs is cracked.I am new at this. what is my next move.HELP
I don't have any experience with breeding keets, but I think you should remove the cracked egg. Make sure your birds have plenty of nutritious foods and minerals (especially calcium / cuttlebone) available.
Is the female tending the eggs? That will factor in to the advice someone might give you.
