For those of you own EEs, do they vary greatly in size? All my chicks are just over 8 wks. old I have one that seems to be an EE (has green legs), but it is way smaller than the others. I've been told it is a roo b/c its comb is already reddish but it looks nothing like our other roo (definately!) from the same shipment. He's one of my favorites so I'm very curious. Any thoughts?
