does anyone know what breed the black and gold one is? And are they a rooster or a hens? Which would seem like a dumb question (seeing how much different they look) but when I was looking on the internet at barred rocks and the roosters had small combs, about as small as my hens! but still I'm 90% sure it's a hen... I REALLY need to know because because we can't name them till we know also at what age does a rooster try to crow and what does it sound? Thanks!
