We have been experiencing multiple nights of freezing fog. Now some of my flock show signs of frostbite. I have good ventilation in the coop. How do I combat high humidity in the coop when the outdoor humidity is 80-100%? I have no electricity in the coop, but could run an extension cord out there if that is what I need to do. We live in central WA, and normaly have very low humidity. I am at a loss as to what to do, and am thinking my only option is to add a heat source of some sort to "dry" the air, and treat the frostbite. What is the best treatment for that? They have a tarped, but uncovered run, that they refuse to use since it snowed. They just look at me like I have stark raving mad.. I'll be and hope someone has some suggestions for me.
