If you are unsure of the sex of your cockatiel, you should take it to a veterinarian for DNA testing. This will ensure that you are providing the proper care for your bird.
I breed my cockatiel and it laid eggs i was told a male?
Cockatiels are sexually monomorphic, which means that males and females look alike. It is not possible to tell the sex of a cockatiel by its appearance. DNA testing is the only way to be certain of a cockatiel's sex.
