We have two pet hens. they have avian pox. I am not worried about the wet causing problems. How do I know if they have that? I can see the pox on their combs, waddles and a bit feet. The chicken that doesn't have it as bad seemed to be breathing (?) with her mouth open. It was hot so I hope it is that but should I be worried? Is there something to do? When is it an emergency and how can I help her be OK? thanks!
