I have 9 Orpington chicks and they are a few weeks old. I have noticed that one seems a little less active than all the rest. He seems like he is always lying down. Even when the others are stepping all over him, he doesn't seem bothered. I don't know if I am overreacting. Maybe he is just a calm, relaxed chick? He does walk around sometimes. He doesn't have pasty butt. Any suggestions? I thought about putting him in his own private brooder so they all wouldn't be stepping all over him and bothering him if he felt bad. He cried so bad that I decided to put him back with his siblings. I am new to this and would appreciate any tips. What feathers he does have seem kind of ruffled almost like a cat when it makes it's hair stand up.I don't know if that means anything.
