How to tell if a cockatiel egg is fertilized?

Question

i got a new girl cockatiel like 2 days ago, and we already had 2 males. and they went in her cage for a while, and the next day she laid an egg. is it fetilized? how can i tell? and it cracked too..and she was pecking at it. is that normal?

Answer 1

If the egg is cracked, even if it is fertilized, it will not hatch.

Answer 2

If it cracked it won't hatch. Female cockatiels will lay eggs whether or not there is a male present, so they won't always be fertile. You can try candling to egg by holding it up to a very bright light and looking for anything inside. If you don't want babies, just throw the eggs away.

Answer 3

was she pregant when you got her? no way did she lay an egg in a day. It is probably infirtile. Let her finish playing with it then remove it. Sometimes a female will lay an egg without mating or even when no other bird is around.
