Hello!! so i just got my chicks today from the post office and one of my black copper marans seems like it's not doing so well it s the smallest out of all the chicks and it seems to be not able to walk very well, it gets pushed around and falls over a lot and usually when they are huddling it is close to the huddle but not actually in it. all the other birds are curious and found there food and water. it also it sits in one spot and rocks back and fourth and than seems to snap back into reality. if someone could help that would be great!! It has a leg band on could that be the issue??
