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 to eat. As far as cocci is concerned, there are 9 types of cocci. Corid treats all 9 types and isnt harsh on the chickens system like sulmet. Sulmet only treats 2 types of cocci and there's a 10 day withdrawal period. There isnt a withdrawal period after using corid.
