Fowl Pox?

[medic4life]

So we have a few in our flock that have been having some respiratory issues. We treated the flock with tylan but nothing changed. Now a few (the worst ones) have black spots so I'm wondering if it's Fowl pox? 3 of them have been mouth breathing, wheezing, heavy breathing on exertion, but other wise acting fine. They still eat, drink, and act normal and the hen still lays daily. We also treated them with valbazen for worms just in case, even though we haven't seen any. Is this Fowl pox? If so what's the best treatment? Can I vaccinate my flock for Fowl pox even though they are all of laying age or older?

To me it looks more like peck marks. The single comb bird may also have early favus or it may just be dry comb.

It look like something else. But can't really see anything on the photos.
