These are pictures of my hen that has been having some problems for several days now and took a serious turn for the worse this morning, when I found her sitting in the middle of the chicken house with her eyes closed and she wouldn't move. We noticed about a week ago she was walking funny and her comb was a little bloody. I thought then she had been attacked by a rooster but then noticed she continued to stay by herself and act sickly. She has some white poop stuck on her vent and feathers but my real concern is her eyes being closed and her crop being puffed up right under her beak....her head is extended up and back as well. She seems to be in distress but I am not sure what to do for her. It may be too late to save her but I was just hoping someone might recognize this as symptoms of something. We have treated our chickens for different illness/emergencies in the past, but never anything like this. I don't know whether it is something to do with her crop or not. Her crop is hard and I don't know if she's been eating or drinking. I have brought her in the house for now just because it is cold outside and she was shaking. Is there anything else I can do for her? I would appreciate any and all suggestions/advice. Thank you!
