Thank you ! He's just fathered quite a few children and they've came in alllll sorts so I was getting curious. His personality definitely matches it. He's the best rooster. Only problem I've had is him being to gentle when he should have been more protectiveI think he looks to me like an Easter eggers rooster. Easter eggers often pop up with single combs like his, the dark legs, the beard. I had some that would've finished maturing to look just like him.
Those above are generally correct. Easter eggers are themselves mixed breeds. But that's why he was sold to you as Ameracauna, Easter eggers are all to often falsely advertised as such.
In either case, I think he's beautiful, one of my favorite colors on a rooster. And if he's got the personality to match you're in good shape.
