I received a variety of day old chicks from McMurray's about 4 weeks ago. At first, all the Phoenix and Silver Leghorns looked identical. At 4 weeks old, I can see a difference now - but I still don't know which is which. Can anyone help me? Some now have more silver on their chests (maybe the Silver Leghorns?) and some have more of a brown color on their chests. Here are a couple of pictures. Can anyone tell me which is which?
