One of my Rhode Island hens started acting weird a few days ago and I have no idea why! She's a five year old, maybe six-seven pound hen, and she just suddenly started being plain weird. Her head sways quite a bit when she looks around, and currently, she can't walk. If she tries to stand, she falls forwards onto her face and has to scooch to get back up. She's obviously trying to eat and drink still, and I separated her and gave her her own box and everything, also took care of a slight bit of scaly mites on her legs, but I don't know what to do! I've checked her out, felt her legs, her neck (which she stretches out and droops towards the ground when I touch it) and basically just all around to try to figure it out. I've looked down her mouth even, and the wasn't anything there! Can anyone tell me what this might be? I don't have any way to take a picture or video her, because I most certainly would.
