Fowl pox or canker?

[EstlHope]

We got a new rooster from a friend. He was properly quarantined and just fine, so about 3 weeks ago we moved him in with his flock. We keep turkeys and chickens, so we have essentially four quadrants in our chicken pasture. The new rooster got in a big fight with a rooster in the next quadrant when we introduced him to the pasture. They worked out their issues, and both of them seemed ok.

Fast forward to 10 days ago, we discovered that the flock had roundworms, so we have been treating them with Valbazen. On December 3rd, we gave every bird in the flock their first dose, and tonight we gave all of them the second dose. They seem to be doing well on that, but when we went to give the second dose, the new rooster had lesions in his mouth. They definitely weren't there when we gave the initial dose of the Valbazen, so they haven't been there for too long, but they look fairly big. I didn't notice a smell from them. Looking at the pictures, his comb doesn't look great. I thought it was scabs recovering from the big fight with the rooster next door, or possibly some frostbite because it's been very cold here in Indiana, but now I'm wondering if maybe it's some sort of pox?

Any ideas what to do or how to treat? I can confirm that no other birds in the entire flock have anything weird growing in their mouths, since we handled all of them tonight. This little guy is the only one with that. He's also a little thin.

Apologies for the aggressive flash, haha. It was after dark.

With all those lesions and no bad odor, I'd say you're dealing with Wet Fowl Pox.

For lesions on the skin, comb, etc. I'd pain those with Iodine.

May be a good idea to sanitize the water, the link below has instructions on how to do this with Iodine or Oxine.
Having an antibiotic on hand might be a good idea as well. Often even wet Fowl Pox will clear up on its own, but sometimes there can be a secondary infection.

Where are you located? I agree that you may be dealing with fowl pox, and inside the beak it may be wet fowl pox. Make sure the rooster is nesting and drinking, and offer it 2-3 times a day.

Ok, thanks. We have some LA-200 liquamyacin, and some powdered tylan. Based on the link, my guess is the liquamyacin is a better option?

Anything to look out for specifically for that secondary infection?

I'm in Indiana. What should I offer it 2-3 times a day?

Liquamycin is probably the way to go.

If he becomes lethargic, if you notice signs of infection, difficulty eating, pus, bad odor, etc.
