Hi, I have two parakeets one is a male and one is a female. On Friday I found an egg at the bottom of the cage but I don't really know what to do I know that I should buy a nest box, but I can't seem to find one in a store right now. Would a cardboard box work? Or a different kind of bird nest? Also, I found out that a parakeet lays an egg every other day, but she hasn't laid anymore yet. Does the male have to be in the same cage with the female? Mine are in two separate cages next to each other. Can someone help me?
