What breed is my rooster?

[Ch8ckenhelp]

Raised this big guy from a week old chick. He was fully black, even as he started to mature, but one day, he started growing gold feathers. He also had one green spot on his brown eyes, which has now turned golden yellow as he matured. And he's REALLY heavy. Now he's about a year and a half old and I still have no idea what breed he is. I feel like he is a mix of two breeds bc of his eye, but I don't know what breeds...
Edit: if you zoom in, you can see the gold spot on his eye.

Not sure the breed but he’s beautiful

I almost said 'gold laced Wyandotte' but with an unfavorable comb. Then I noticed his leg color was wrong. I think he’s a mixed breed.
