Hi again all--just have some questions about my plan... 1. do you HAVE to put your 2x4's from framing onto concrete piers or is that just extra protection from rotting? Can you just treat the bottom 2x4's with some kind of sealer/anti-rot stuff? 2. one plan I saw had the hen house sided with fenceboards. Then they also wanted you to caulk the inside seams AND put plywood on the inside walls as well. Is this overkill? Do you have to caulk if the boards fit together well? Or is that inviting drafts? I live in northern CA where it's pretty warm year round, but it does get a little chilly (down to the mid-30's at the lowest) in the winter. If I do have to put plywood on the inside walls, can I just pick a thin thickness and not 3/8? 3. The same plan has you with just a mesh-top to the henhouse, no boards up there. Basically a big box with mesh on top, and then the corrugated plastic roof placed on top of that on rafters. Is this too much open-air? Or is that good for ventillation? I think that's all for now...I'm trying to tweak these plans to fit my space and it's really a lot harder than I thought. I think I'm obsessing a bit.
