My chicken was fine one day and the next afternoon was unable to move in her hutch. She can only lift her back and flops never lifting her head. I have been feeding her wet food with serynge and antibiotic water with an eye dropper. My other chickens seem fine. I don't feel an egg. Her poop seemed a little stiff like she was dehydrated but other than that not strange looking. It did have a lot of pebbles in it, but I read that that was normal. Her feathers look healthy. Her eyes look normal. I just can't find anything that it would be. She doesn't seem to have many symptoms besides just inablitly to stand or lift her head.
