I have a male and female that were buddies but not mating. I put them in the aviary with 2 other male cockatiels. It looked like the female was going to pick another older cockatiel that is a proven breeder but lost his mate.
But she changed her mind after a week and went back to the first male she had been with. (not proven breeders)
I separated them out in separate cage with a nesting box as there was a lot of fighting going on.
They are always in the breeding box and are now sitting on 3 eggs, but I have not seen them breed once.
Any thoughts? are they breeding in the box?
