i just moved our 7 chicks into a larger brooder made from a giant Rubbermaid crate. Their old one was clear plastic. This one is gray with a black lid for te floor. They all started scratching and pecking the black like crazy when I put them in there. They are acting weird and frantic. Should I put them back in the old brooder? Will they calm down? I'm really worried. Could they hurt their beaks?
