Last night when I checked on the girls, everything was fine. This morning when I went out to the coop I found my 7 month Australorp (Rue, my favorite) lying at a weird angle. When I picked her up, her head rolled around her neck and she seemed to have muscle problems. Her body temperature was low but she was still breathing, so I took her to the house and stuck her under the heat lamp. I held her until she passed on. This is really upsetting because not only was she my favorite, but I'm afraid my other chickens are at risk! If you have any idea what could have happened to Rue, I would really appreciate it! Thanks for any help you can offer!
