I have a female cockatiel right now, but I'm thinking of getting a second one. A breeder I know has 3 available babies, and 2 are males. If I get a male, will they try to breed (if they like each other, that is) even if I don't provide them with a nest box? I will be keeping them in separate cages, but they could always try to mate when they are out playing together, etc. I definitely don't want eggs or babies on my hands!
