Hi, If I were to compare the 4 chicks @ 2 1/2 months old, I have 2 alike and 2 different. 2 have larger combs. So I think I have 2 roos.... Can you offer opinion? Is the Japanese banty with comb in the picture a roo, do you think? The 2 pullets pictured are RIRXDel. Ruby and Freckles...you can almost see Freckles lovely spots.
