i would go for a barn yard mutt!! i got an EE mixed with a sussex roo and he was the most gorgeous thing id ever seen! he had a cream colored body with speckling all over his wings and tail feathers, his wings went from a nice very light brown to a deep chocolate brown and he had a nice beautifully speckled green tail. mutts are so much fun if you are only going for looks. and he was the sweetest boy ever. he was a good protector too. a hawk got him tho. we burried him next to the corn field.
However I am a newbie and completely unfamiliar with adding them/having roo's soooo I may need to research a bit and I need to decide if that's what I'm adding seeing as how I orginially planned on adding a RIR roo and pullet for some brown eggs and chicks...Idk how two roos would do in a flock of 9?
