My chickens and turkeys got fowl pox this year I think. The chickens seemed mostly fine just the bumps and more tired and lazy than usual, they also ate less. One of the turkeys got the wet type and I swore multiple times she was gonna die. She was up and down for 2-3 weeks. Much worse on cold days, much better on warm ones. I gave her electrolytes and used vetrx. Vet rx will help keep the respiratory system open so they can breathe, because her nose kept getting filled with mucus.
