This is how it is with one of our NH hens. My girls named her Rascal. She had a hip displacement last summer at about 3 months of age. All sites I referenced said it would be better for her if we processed her because even if she ever walked again, she would never lay. They said that hip displacement is one of the most painful injuries a chicken can endure. So I mourned for days while I had her nesting in a plastic tote in my bathtub. Well, since I had no sites that helped with "splinting" her hip without a vet doing surgery, I just decided to do what I could for her. I got breathable gauze and folded her leg up as normal as possible and wrapped it. Just her foot was unwrapped. I brought in one hen from the flock to be her bedmate, since the hen I chose had just lost her best buddy to a fox and was also depressed. She learned after about 2 weeks (!) of laying down helpless to hop around on one foot. After about 4 more weeks of hopping, I ungauzed her leg (swapping out gauze ever weeks or so) and she hopped on one foot while occasionally using her foot to balance...long story long

she now walks 100% fine (she's a year now) and has eveb begun to LAY!!! Love can do much in the way of encouraging. The other hens used to be so cruel to her as the only non-layer. But she earns her keep now and she is my best hen buddy. She even says "please" for treats. No joke.
