Hi, I'm brand new, never had chickens before. I got four New Hampshire Red chicks at less than a week old. They are now 10 weeks old. I noticed a few weeks ago that one of my hens had a toe on each foot that curls inward. Over the last week and a half, one leg is now almost completely turned backwards and the chicken can't walk well. She still gets around, but spends most of her time sitting. Is this common? Can she live this way? Can I do anything? I'm trying to get a good pic but it's hard.
