Mystery chicken gender and breed guess??

[KMG]

This little one was a barnyard mix that we got from someone to give to our broody hen. It's about 10 weeks at this point. I thought it was a roo pretty much from the start but lately it's acted more like a hen. It's just always been pretty big and got it's comb and wattles fairly early. Bonus points if anyone has a guess on what breeds it may have!

I would guess a Black Copper Marans cross and it's a cockerel.

I’m leaning towards cockerel as well

It's a cockerel, pullets don't get wing bars. Do you know what breeds they had? That would help narrow it down
