I started seeing this on my rooster about a day ago I was wondering what it was. And if it’s dangerous how to treat it

What's the temperature like where you are?
Coop stay dry with ventilation?
Looks a lot like frostbite, but also as if he's being picked on.

It looks like he has been pecked or has run into some fencing try to fight or escape. It will heal in a few weeks without any treatment.
