Hi, I'm really new to backyard chickens. We had to return a rooster and came home with two chickens to add to our flock. One looked pretty...ugly. I assumed it was from being bullied at the farm, but then I read about fowl pox :/ I'm freaking myself out! Does this look like something I should be getting checked out? He has no tail feathers and his...umm head thing is all scabbed up.
