Frost on inside of coop walls is from high humidity inside coop, thus a lack of ventilation - not a lack of insulation.I am thankful mine are okay..noticed some frost on their walls...INSULATION THIS SPRING.. lots of goodies being fed. I think thats the trick but a bit of froastbite on my Roo... they wont let me touch them so well see what happens come spring
40 below kast night..High about 7 below..TOMORROW 17 YIPPIE!!
So say.....more ventilation this spring!!
