Feather number 2. Found in a chair (now how on earth did it get there?) near the cage. It's a biggie---a clipped primary wing feather, full quill. only about an inch of actual feather on it and there is a small white band about halfway between the end of the quill and where the feather starts. Feather #1: The feather from the other day was clean at the cut line---it wasnt frayed, didnt appear to be chewed but there was a beak mark further up on the feather. He's also molting though other than these 2 feathers Ive not seen anything but an occasional down feather. Good news is he's got a TON of new quills popping out on tail, wings, etc...a lot of primary feathers starting to come in and his preening is less aggressive--not attacking the feathers so much as he's just doing what appears to be normal maintenance. He feels like a porcupine. How do I know what's normal molt, what's an accident (falling in cage) and what's feather destruction/plucking?
