Do any of you have a cockatiel that lays eggs. I have a cockatiel and a parakeet in the cage together. The parakeet is about 2 and cockatiel is about 3. I have had both parakeets and cockateels in the past but they never layed eggs ! Can they lay eggs without being fertilized like my hens ? Could they breed ? I keep finding a little egg in the bottom of the cage and I think it's to big for the parakeet to lay. I don't know the sex of either one of them but IM assuming at least one of them is female huh ? This happens about once a month or so. Weird ! IM getting ready to put a nest box in there and see what they do ?
