He is on the bottom of the cage, it seems like his feet are crippled and he can't perch. He is still eating and drinking. He started to lose his feathers a year ago and they are not growing back. He is also chewing on the paper we use at the bottom of the paper like he is nesting. I think it is old age and he is preparing to dye but no one can tell me anything so far unless they look at him and the only vet we trust is on vacation. Anyone know anything about this.
