I'm confused..it's been really dry but I think one of my hens has wet pox. I noticed a swollen spot on the corner of her beek. Inside her mouth is a flesh color ulser looking thing. At first I thought it was food that might have built up in the corner of her mouth. I tried to clean it out but it's attached. So what do wet pox look like? And what should I do? Medicate? Or let it run it's course like dry pox? Thanks for any help!!
