I have a Rhode island red hen about 2 yrs old who has not walked in a week. I found her in the coop, with a completely laid egg, and crap all around it. I removed the egg, washed her butt down with warm water. She will not stand at all and only balances her self with her wings, she has an appetite still and is still drinking. I've moved her legs and can feel no breaks (not an expert by far) legs look to be normal. There are 8 other hens in the coop with her, all healthy. Anyone care to take a guess as to what may be wrong? any help is much appreciated. I'm 3 hours away from an avian vet. Thanks!
