I have three 5 week old ameraucana chicks. None of them have any comb development. They are all pretty sweet and not chest bumping with the wild Black Copper Maran boys. Looks to me like 2 splash and 1 black in coloring. But I am wondering what Ameraucana chicks look like at different stages of development. How fast do they develop combs or any way of telling which are pullets/cockerels? I'll post some pics when I get home but I would love to see pics of your chicks and older and what the little cockerels look like at this age vs the young pullets. really I just want to see pics of your babies!!!
