Handsome!
The reddish flush is likely hormones, you'll see that in roosters, cockerels and even hens sometimes when they are "mature".
I don't see purple, but if you do, then that would indicate some brusing.
He's standing with his left foot turned in just a bit, feel of that joint to see if it's swollen or tender.
Recheck his foot pad just to be sure it's not raw from the cold and moisture.
If he's limiting his activity, then you can decide to keep him with the hens and let him hang out, but if you think he'd relax better by being caged, then cage him. I'd keep him near his hens if at all possible.
I'd also start giving him B-Complex daily. 1/2 tablet, he's a big boy.
Hopefully this is just injury. I'm not seeing anything that says frostbite right this minute, but it can happen.
You mention you are in NC, I sure hope you are safe and o.k. from Helene. I'm in WNC, I was very blessed to not have much damage, but my heart breaks for many many N Carolinians.

View attachment 4001229Hey so I went to check up on him this afternoon im not sure if it’s raw but his leg looked more reddish I’ll take some pictures tomorrow and clean his leg to get a better picture because I’m not really sure. I also did check his foot pad and it was a bit swollen I don’t know what I’m supposed to put on it. Also thanks for the help
