Hello, I have a 2/3 year old RR chicken with a distended abdomen, ruffled feathers, watery poop, and is lethargic. She is sill eating and drinking. This has been going on for over a month and she did seem to be getting better until last week. However, her abdomen has stayed the same. I bathed her in a warm tub and checked for egg binding but found nothing. Has anyone else had this problem?
