We only have 2 hens, they live in a wooden coop but spend most of the daytime outside in the yard. We feed them layer mix food along with oatmeal and fruits and vegetables. Their water is changed at least twice a day. We use pine shavings from the feed store for their bedding. The smaller of the two chickens started acting strange about 2 days ago. She is usually very active and runs around the yard when I try to put her inside the coop. Recently she has been moving very slow, does not try to get away from me and does not seem to peck at the ground and bushes like she normally would do. She seems to be eating and drinking normally but has not been laying eggs for the last 3 days. Her combs seem kind of floppy and are not as red as normal. She also has a bit of poo on her bottom. Does not seem as clean as she always has been. We really love our hens and are very worried. If anyone has any suggestions, we would be most grateful.
