The lighter yellow hen has some barring throughout, and the darker one is more reddish with black tips on her tail. The black hens look like my sumatra rooster but are larger than him. They have black legs, and face and very small combs. One of the black hens has yellowish legs and brown/red feathers below her beak. I bought all the hens together at an auction, and the rooster was a totally separate buy. Any info will help. Thanks!
