Injury After Attack By Other Budgies

[Kevs Clark 0]

I have two female budgies and three male budgies. They were getting on well but then I found one of the males in the bottom of the aviary looking like he had been attacked. His tail feathers were missing and he was missing a lot of feathers from his wings. My biggest concern is that one of his feet was bleeding but stopped after a few minutes. The claw is now all curled up. It has no movement in it and he is not using it. I have him in a small cage inside and he is eating well and quite chirpy but he just stays on the bottom of the cage.
