Today, after her bath, we noticed my Ollie, a blue runner, was bald all on her belly. She had been diapered today (so we handled her bottom region, I even felt the feathers there when sliding in the diaper insert) and we did not notice any balding until she was in the tub. This is Ollies first time being diapered in a very long time (months). she seems to have eaten the feathers as there were none in the tub. She is isolated with only one other duck right now who we've observed and is NOT plucked her. I'm pretty sure she did it to herself. Any ideas on why? I'm going to call my vet in the morning but I wanted to get some ideas before I take her in... Any help would be appreciated.
