Fowl pox is a virus, antibiotics would be ineffective unless there's a secondary bacterial infection. You'd just have to let it run its course if in fact it's fowl pox. They get over it in about a month, more or less. Eggs are safe to eat. Mainly mosquitos carry the virus, try to eliminate standing water on your property. I'll ask someone else to take a look at the pics you've provided. But it doesnt look like pox to me.
