Came home yesterday to find one of my 6 month old pullets hiding in a corner of the coop. She will kind of hobble around using her left wing for balance, but she doesn't extend her legs so she is moving on the foot and lower portion of the leg. Toes are close not the normal extended. No outward signs of trauma, i ran my hands up and down each leg, and wing and didn't feel anything strange. She will perch and grab onto my arm as she does. I do have 2 young roosters about the same age that are rather over zealous and she is younger/smaller than most of the hens. Right now she is segregated in her own area and is moving around (slowly), eating, drinking, and moved into the sun to relax. Any idea on what the issue could be? Injury or disease, or thoughts on what I should check next.
