I have a blue crown conure I found him lost 3 years ago these days he has been regurgitating his food He eats he drinks water and he regurgitates every time I change his food, the stools are normal, his weight is correct he is active I think he is in the mating stage because he has become a bit aggressive and plucked his feathers from the top of one wing. He doesn't have a partner and he doesn't see other birds. He used to talk a lot and since he started doing these things he almost doesn't want to talk. If anyone knows why?, please help!!!
