I bought my first Flock this year as well. Mine are six months old now, and I think I will be able to tell the boys from the girls better when I start hatching. The combs on the females are much smaller, especially as they get older. They look to be purebred, and if they are I am saying the other blue is a girlthat one had a flaten comb and is not the same as as the other 2 the other 2 have a well shaped peacomb I hope its a pullet.
My easter eggers are easy sexable but the AM are difficult, y bought adult ameraucana in the past, but never chicks or eggs i have hatch these may29,2015 and they Are just starting changing voice
