Bald spot on my roosters leg

[KC Chickens]

I'm not sure if this is something to worry about, but my rooster has this bald spot on his leg.
He is currently in the indoor chicken hospital as he suffered some bad frostbite. He is almost healed up but I noticed this balding starting to happen.
He acting normal, eating, drinking, looks happy.

What could this be?

The photo is unlit and blurry. Could you please try again? Move the rooster somewhere that doesn't have bright light behind him. Instead, shine a light on the leg lesion. This will help your camera focus on the detail of the leg. Also, wet the feathers around the lesion and smooth them away from the area so they don't screen the detail of the lesion.

Photos are not worth a thousand words unless you're a Pulitzer photographer. Including a description of what you see is necessary to help us make sense of what we're seeing.

Where did he suffer frostbite?

To me, the bald area looks like picking or plucking. Observe him to see if he's picking at his leg and check him for mites/lice.

He had it on his comb and waddles.
I did just discover that my chickens have mites or lice. Not sure which. They are small and yellowish.
I will be treating with bronco spray and hope it does the trick!

You can use Prozap or Goldstar permethrin garden dust from your local feed store during cold weather. Put it in a sock and dust the chickens like a powder puff. Lice is what it sounds like, and they need to be treated at 10 day intervals at least twice, to get both the live lice and then the newly hatched eggs.

Ok great! Thank you

Lice usually lay clumps of white to grayish eggs at the base of feathers.This article has good pictures of lice and mites:
