Doubtful...You see mites?

Haven’t seen any, although I suspect

Why?

Why?

Due to him constantly grooming and that I suspect he had contact with another chicken flock or animal (he went missing for an entire day and an entire night)

could be he's got scaly mites starting but more likely I would think irritated where he was recently injured. Do the legs look like the scales are lifted, if so he may have scaly leg mites and you have to put oil or Vaseline on the legs to smother them, could be from recently trying to defend him self so doing so might be a good idea just to help sooth and protect the legs

That means nothing. He is probably grooming because his leg is sore..

Redness is often hormonal and normal, I don't see anything alarming. This manual describes how to examine for a fracture and how to splint various ones. Without an x-ray that is the best you can do. If you do splint, then pad the splint so that it doesn't rub and irritate, and don't wrap too tightly. Check often for swelling and make sure there is no loss of circulation. If you can get a video of how he moves, and favors it, it might help others to see. You can post to youtube and put the link here so it's viewable. It's also possible that it's just badly sprained, strained or bruised. With a few days of rest and limited activity it may improve. I would crate him for now, so you can monitor his leg, limit his movement and watch his eating and drinking.

This ^^ I agree, the redness looks hormonal to me as well.

Try limiting his activity to see if that helps. He may be grooming at the leg because it hurts.
You can also offer him an aspirin solution for pain, but he also needs plain water available, some chickens will not drink the aspirin solution too well since it's bitter, but you can try sweetening it a bit with sugar or honey.
Aspirin solution is to dissolve five (5grain (325mg)) aspirin tablets in a gallon of water. Make fresh daily - drink free choice. Of course you can reduce that and make a quart if you want to.
