Neighbors Rooster

[ChickChic00]

Any idea what my neighbors rooster is a mix of? I have no information on him. Neighbors roosters (multiple huge ones) keep coming over to our yard and fighting our chickens that are in pens. So I caught him so that my father won't hurt him. Neighbor has been told over 6 times. Rooster is sweet btw, thanks so much!!

Probably buff Orpington crossed with a blue breed. He is pretty.

I figured a buff, but I didn't know what the blue had come from. He is pretty though! Thanks!
