Seriously late reply but just did a quick search and found this conversation. I had a wild cock pheasant join forces with my hens (by that I mean he ate their food, roosted in the shed etc), and a month or so later we had a hen hatch 11 eggs. Only one survived to maturity, and she (Zipper) is most certainly crossed with the pheasant. She looks different to all the other chickens the same hen has hatched with the roo we have, she digs ditches and when she jumps the fence into the garden she sort of swoops - a lot more graceful than my hens! She's about 6 months old now, I'm not expecting her to live that long but it's fun having her. If interested, I can post a picture. She's a gorgeous caramel colour with black striped tail and black tipped wings, and a black stripe across the top of her head.
We ended up having to get rid of the cock pheasant though, he was distressing my hens and fighting with my roo. But his offspring is definitely alive and kicking!
