Random Rooster joins my flock

So a random white leghorn Rooster showed up two days ago. Thought he'd leave on his own but now he's foraging with my chickens and is sleeping in their coop! He's been pretty nice for a rooster and is friendly to me and the chickens. Hasn't attacked any of them. Just kind of random he showed up. He must have come from pretty far because he's not from my nextdoor neighbors coop or the neighbors anywhere close by.

He's got a loud crow and is confident so decided to call him Foghorn after Foghorn Leghorn. He's a Cockerel it looks like, full grown but less than a year old. He's already friends with my one black chick for some reason and walks with her as a personal escort
