Hybrid is my guess. The gentleman I got him from isn't a breeder so far as just throwing in whatever he's go in the same pen, he is a good breeder that I think was not given a full disclosure of the parents lines and he breed to his knowledge of.
His parents were bought in a lot of several breeds at a auction and they were WLH... Him and his brother were hatched and being Roosters they were sold as WLH. That's all I know, I was looking for a trio or chicks and a friend of both of us asked if I would like to get them, I didn't want two...
Speaking of Bresse, I traded a few of my extra roosters for what we're supposed to be Bresse pullets. I'm not going to assume that they are that. If so, I have 4 that are just shy of 4 months old and they are actually pretty babies. I don't see them getting as big as giagantor the white Wonder...
He's massive also. He's roughly 20" and 2 and a half ft wing span. He's 10 months old and weighs just over 6lbs. Maybe I was misinformed or I misunderstood their breed traits and he is just on the larger side of these growth ranges. He's a great Roo, still a little flighty and not a cuddle up...
I bought him as a white leghorn, but he just doesn't seem like that's what he is to me now. He is huge, and his comb is straight up, white ears, slate grey legs, pure white feathes
