Thanks couchin & howard. Im in WI, my coop is insulated inside my barn and I also have a heater in it too, but not enough. It is very cold. My rooster is 10 lbs can't sleep on bar, sleeps on floor. I think the moisture came from the way he stept on the dropping.
Time of below 0, my rooster got frostbite on his feet. Now the toes turn black. I want to heal them but don't know how. Any idea or experience, please let me know
