Hi! I received 17 chicks from McMurray's ornamental layer collection on 4/27. Does anyone know what these are? Chick 1 is very sweet and docile. Likes to sit in my hand Chick 2 is all white and quite a bit larger than everyone else. He/she is starting to get feathers on her neck that look darker than the white ones on her wings. Chick 3... Thanks in advance for your help!
