I have a polish chicken and i think she might be sick-- but i don't know what she has or how to help her!!! Her symptoms are: She looks kind of puffed up and ruffled, almost a bit chilled looking, She also smells pretty bad, and she usually doesn't smell! She is kind of Roach-backed, her back is up and curved and her tail is downwards. She doesn't walk around much, just a little bit. Her poop seems pretty normal, maybe just a little bit liquidy. There is no blood in it from what i've seen so far. I don't think she is egg bound, as i checked already. She looks like she is eating and drinking. I just don't know what is wrong with her and i am really worried, as she is my favorite hen and i don't want to loose her! Please help!!!
