hi, its my 1st time on this site, and hoping someone can help me with a few questions about my birds, i am having problems getting my parakeets to breed at all, and my cockatiels bred once and we had to pull the babies because the parents stopped feeding them, and now i can get them to breed again. am i doing something wrong? am i missing something on them, we let them out the same as always, we feeding them all same same diets ie vegetables seeds fruits. and just don't understand why they won't breed?
