My brown leghorn won't use one leg. She was fine this morning but when I came back later to give them fresh water she wouldn't even stand up. At first I though she was just about to take a dirt bath, but she never got up. I stood her up but she was only standing on one leg. She used her wings to keep herself up right. I looked at her foot and her leg but I didn't see anything that looked out of the ordinary, the only thing I could tell was that her toes were not curled like they usualy do when her leg is up (like when I pick her up and she pulls her legs up), inoted they were sticking strait out close together. I set her in the coop because I found her in the dirt and it's cool and windy out, I didn't want her to get cold. She got up from where I put her, hopped a bit and sat back down after almost falling a couple of times. This is my first flock of chickens and I don't know much so I would realy appreciate anything you guys have to offer, like, anything specific I should look for or something. Thanks.
