Cochins are cold hardy...oh, but they have feathered legs. Sorry. Delawares are great, friendly birds, but they all follow one type. However, they're not a solid color, and the lovely neck and tail feather tips look SO regal in a group.
Yes, there are a lot of Sussez variations. I don't have any, yet.... Sounds like a good choice.
Although I would opt for Easter Eggers just for the great variety in bird AND egg colors!
I love my multi-colored, incredibly varied flock.
