I have this ongoing discussion with my husband about the venting and the moisture level in the coop. We do have some small vents built into the coop, but I think we need a bigger one. He tells me I'm too worried about it - the coop is fine. We're trying the deep layer method of wood chips in the coop the winter (our first year with chickens). The problem is, the chips become a frozen mass. I try to fluff it up each day, but can only do so when the temps are above freezing. So my question... Is this mass of frozen wood chips a sign of too much moisture in the coop? Or is it normal. We have snow on the ground and it's fairly humid outside anyway. Still, I can't help but feel that I'm not doing the girls justice here. Feedback would be appreciated! Many thanks.
