We got this chicken when we knew NOTHING about chickens. It was about 17 weeks then. It was sold to us as a RIR hen. I have done some research and can tell it is obviously not a RIR! But is it a hen? It is now almost 30 weeks. It hasn't started to lay yet, but it does not crow either. We have two rosters that do crow. Our large game roo is all over my other hens but I have never seen him try to mate with this bird. It does have some strangely long feathers on its back compared to my bantam laying hens, but I don't have any like her to compare. Is this just a large hen or is it a roo in hiding? Her comb has grown even larger than this pic and her spur spots are noticeable. She-it is also very dominant!! What do you think?
