For now, I have my White Marans hens in with my Lavender Orpingtons. I set some eggs from that group and ended up with my Lavender chicks and the following from the White Marans Hens. The coloring is confusing to me - and it appears all the black chicks are pullets and the other (Cuckoo or Barred Rock coloring) are cockerels. Any suggesting as to why this has happened? I had a white Rooster with the white marans before and got all white chicks, so unsure about this paring....thanks for any ideas you can give.
