I was sold this bird as a black sex link. When I purchased it there were few down feathers left and it was mostly pin feathers. Legs are yellow with a black wash. None of the other 7 chickens including the 2 roos ever challenge this bird. Feathers are now black with a green sheen except on the breast where the feathers have fewer than a dozen brown specks. What is the consensuses on the gender/breed?
