Ok. Have several pens. some with cover some with none. It seems I wasted my time with the covers. The covered ones do not cover the whole pen just a place for them to stay dry if raining. but..................they do not use it as all. The stand in the rain. Can the rain hurt them at all? I hate to see them all wet as they look like drowned rats!!!!!!!!!!! Do I really need to have covers ove rthe pens. I use dog kennels for my coops and I have just netting over some and again, it seems the rain does not bother them at all. So is a water proof cover really need. Whewwww, I got long winded there for a simple question.
