Augh! Neighbor's dog got one of my hens. Silver Laced Wyandotte, about a year old, good health otherwise. No blood or puncture wounds that I could find, just a lot of feathers missing on each side under her wings. But she's limping on one leg. After the dog dropped her I put her in the coop as she was in a light shock. She just came out wanting to eat but that leg won't hold her up. She hops, lays down, pecks around, gets up and does it again. It doesn't seem to be broken and when she puts it down, the toes are in the correct position. It seems to be fine till she puts her weight on it, then it gives way. Any ideas what's wrong and how to care for her?
