Because we know our bird is doing her single mom thing and there is no guy around the egg is definitely infertile. It is not fair to the bird to allow her to try to hatch the egg for weeks.Our cockatiel Popcorn is a prolific egg layer. To the uninitiated many female birds, especially cockatiels and lovebirds will lay eggs whether or not they have a guy to help around the cage.
There you are drinking your morning coffee trying to get ready for work and as you breeze by the cage you see an egg lying on the grate.
