What could cause my cockatiel to be losing his feathers?
I have a 2 yr old male cockatiel. He is well fed, watered daily, and has a large cage that he shares with one other cockatiel. He started losing feathers about a month or so ago, fairly slowly, but lately it seems to have gotten worse. He has lost most of the top feathers on his chest and a few on the top of his head, including a few crest feathers. Is this what molting is, or something else natural? Any information would be appreciated. Please don't leave a common sense answer like, " take him to the vet". I just don't want to go to the vet if it is a natural process or an easy fix problem. These are the first birds I've ever had, please help!
