Can you tell what gender a BCM chick is at 2-4 months of age? Just wondering. Someone local has chicks for sale, 2-4 months old and I just don't want to end up with any roosters! I haven't heard back yet, but the seller may know what sex they are already. I just don't want to get stuck with some off cast cockerels since I just got rid of six extra roosters a few days ago!
