I noticed that one of my hens has a limp today. When she walks, she swings her lame leg around and almost hops around. When I inspected her, I noticed that it felt like her leg was sticking out at the hip a little. One side of her hip is smooth and normal, and the side with the lame leg feels like it has a bump where the leg would go into the hip. Could this be a broken or dislocated leg?
