I am used to my own Wyandottes but I have never had BLR chicks before and I have read that they are harder to sex that other types of Wyandottes. I have noticed with mine that they're easy to tell by their combs & wattle development(in boys), Is this the same for BLR's? I am picking some up soon and was wondering if anyone has any tips so i'll have a better chance of picking out pullets? I don't know how old the babies are. Thank you!
