My two year old barred rock stopped laying one month ago. But seemed healthy otherwise. Ate and drank fine. This week she has really watery diarrhea. Started white then green now yellow. She's very listless. Waddles are red. She looks fine but not eating much and seems to be drinking alot. She did have scaly mites which I treated her for. She is missing feathers around her vent which I thought just might be from the rooster. Her vent seems okay. I don't see lice and crop feels empty in morning. I fed her yogurt and have acv in her water. She is separated from rest of coop.
