please help! Found a very young bird (6mos) in a small sanctuary next to my house. Another neighbor has been feeding it but I caught it last night & have her isolated before flock integration. She's very thin and smells terrible! She has a bad smell coming from her mouth but the crop is empty feeling??? Nothing there. I pulled all food & just have acv h2o to start sour crop treatment but does this sound normal?? She really smells. Checked for injuries, just has spots where blood feathers are coming in with what looks like drying wetness under her wings. old injury? any ideas? am I on the right track?
