I went into my chicken this morning and my one buff oprpington hen is completely paralyzed. She can not get up her legs are stretched out behind her. I have no clue what could be going on she is not walking at all. I'm just so worried for her. I am at work right now I did not get take a picture. She does not have bumble foot because I checked her feet. Her toes are moving just not her legs. Can anyone tell me what could be going on.
