I have these 2 ameraucanas i got together ....they were hatched together. I am suspicious that the one with the redder comb is a rooster. I have 2 wyondottes that have combs growing at different rates but what is worrying me about the ameraucanas is that they dont really grow much of a comb to begin with. So if anyone has any ameraucana roo's for comparison i would appreciate any input. These are about 10 weeks old. top 2 are 'him'? last one is her. What do you think? If its a roo, I think he is going to be so beautiful.
