I have a Rhode Island Red, she is about 9 months old and hasn't started laying yet. Well I moved all 7 of my hens to a permanent coop that is 8x8 with a 20x8 run. However, after a couple days she refused to leave the coop, she sits on the floor all day. At first I thought she was broody as when I went into the coop to clean it she would become aggressive and peck at me if I came in more than a couple feet. I made sure she had food and water inside the coop and she slowly became lethargic. She now will let me get close enough for me to pick her up and move her to a separate in-closure inside. Now here in the question. When I picked her up I turned her over and she looked like she had poop covering her bum. None of the others have this issue and she in uninjured and very clean other than that. When she is standing on the ground she looks like she hunched her back and droops her tail toward the floor. She also doesn't hunker down like the other chickens. I'm starting to get very worried that she is sick. I have never had one of my chickens do anything like this before. Any help will be greatly appreciated. Thanks.
