I got 6 Buff Orphington chicks from RKO Friday evening. Last night I noticed the littlest one was limping. It's really bad. She is not putting pressure on the one leg at all. She can get around, but the other chicks knock her over and run right over her. I don't know if it even hurts to lay down because last night she was trying to sleep standing up. If you pick her up and hold her, she falls right asleep in your hand. She is eating and drinking, as long as another chick doesn't come over and knock her down. Then she just gives up. What if her leg is broke? What do I do? It's so sad.
