I recently bought 3 golden campine hens and a rooster. The rooster is the oldest of them all and the oldest hen is around 18 weeks and she crows. The chicken to the right is the rooster in the pic and the hen in question is on the left. The lady I bought it from said she was a hen. It has all the markings of a hen and lacks the colorful pointy saddle feathers. Why is it crowing? Could it be a hen feathered rooster?
