Hi. Went down to coop this morning to get the chickens day going and noticed one of my pullets head was not "up." It seemed hunchbacked and I thought that one side was bigger than the other at the shoulder area. I am new to this. Then I realized that all the ducks were out, the other hens were, but the other pullet was not out. Went inside and it was laying limply by the feeder. Wrapped it in a blanket and brought it inside and it sounded wheezy and was "moaning." The eyes were white. Called others with chickens and they said to put the ill chicken out of misery. The other one now has it head up but still looks like it is protecting the one side. I have no idea what is going on. Any ideas? Thank you!
