Just went thru this with my flock. The eyes were my concern. I used all of the medications you mentioned but never went to the vet. I would wipe out their eyes with warm water twice a day so they could see. Put the oxy in the water and used the gel in and around the eye for a few days then went back to just warm water. Also used VetRx down their throats. The pox just ran its course which not much you can do. The eyes will clear up too it just takes time.
