A few days ago she was out in the yard and her whole back end was covered in runny poop. I brought her in for a bath and let her back out. She was eating and foraging and acting normal. Today her back end is covered again, she was in the coop with her butt drooping. Came down in to the run but wouldn’t jump out to join the others in the garden. She seems lethargic. I brought her in and gave her a warm bath. Checked for mites/worms/lice and found nothing, although I’m pretty inexperienced. She has not started laying yet, but I checked her vent for an egg and nothing. She has been laying around not interested in food or water, comb and eyes look normal. She’s currently isolated with her food and water, water has vitamins and electrolytes and apple cider vinegar. Besides the poopy butt and her lethargy it seems she is fine. I don’t know what could be wrong with her. Her poop looks normal but runny/watery.
