This may sound odd, buy my rooster has been introduced to cougar hens. They are a few years older than him but I swear her was dancing of for them, he was cirlcing one and was doing this weird thing with his wings, he wasn't hurting them, I haven't seen him get it in with nay of the chickens, but he was doing weird things I havent see before.
You saw the dance I mentioned in post #15! He is trying to convince the hen to allow him to mount her. If she decides she likes him then he is in business!
