I hatched some barnyard mix babies from my own flock. They are 7 weeks now. Dad is and EE/mix and has a green sheen on his tail and wing feathers, moms range from RIR and welsummer. My question is, if some of the babies are showing some green sheen on their feathers here and there, does that indicate a cockerel, or can then pullets get that too? This may sound like a really silly question... but I figured it didn't hurt to ask!
