DONT give them oil, bleach, nor ACV in corid treated water. That concoction can do more harm than good. When you're finished treating your birds per instructions in post #22, you can put 2 tablespoons of ACV per gallon of water out for your birds to drink...nothing else is needed in the water.
Fowl pox isnt transmittable to humans, eggs are safe to eat. Most of my birds have been through dry pox and are immune to that particular strain. I didnt give my birds any antibiotics nor vaccinations. Fowl pox is a virus and antibiotics dont treat virusus. Even if vaccinated, the eggs are safe...
Generally, wet pox can be seen as lesions or sores in the mouth, esophagus. Here's a link to read regarding both dry and wet pox and what to look for.

Keep in mind that fowl pox is contageous. If you introduce the infected birds into your flock, guess what? No telling what other problems they have as well. Think biosecurity.
