Hello. I built a new coop out of pallets. I used all used materials. I used some barn tin that I had and up to this point my coop has been dry and worked beautifully. I also insulated it with plastic, cardboard and wrapped my whole coop in tarps. The problem is yesterday we had treacherous downpours and the tin leaked. It didn't get my litter wet but the cardboard on the back and one of my nesting boxes got wet, not soaked but wet none the less. The roof lumber is wet also. It was 75° yesterday. Today it is going to rapidly drop and tonight it will be 23°. I am going to change out the cardboard and try to stop the leak. I am afraid that moisture that is in the coop will cause frostbite. I am wondering what I should do with that roof being wet because no way will it dry out before dark. Could I paint it, or cover it with plastic inside? I am really concerned my girls will get sick. Any advice would be greatly appreciated.
