OK, I am fixing up an old building for my as-yet-not-even-ordered chickens, I want everything in place before I get them, and its too cold anyways and the breeds I want arent really available...BUT I have a couple of questions. 1) This building is an old brick shed my grandad built in the '40s. He even made the bricks himself, as all those old German DIYers did. Its a really cool building, but I have to reroof it and do some general repairs. It looks like it was intended for chickens...slanted roof, south facing all in all a good setup it seems to me. I have yet to find any real reference to a solid cement floor/brick structure and I am about 75 pages into this thread (of 198!) We get some cold weather, down to the occasional teens, wind chill big time and snow sometimes, nothing really below that, and not for too long at a time. We do go above 100 from time to time in the summer, but it's so dry I am not really worried about that. The question is...Would this tin roofed, all cement/brick building (15x20 or so) get to cold and damp in the winter for a comfy coop? I intend to insulate the roof, just to keep the rain noise down some and hold in some heat. Thoughts? 2) I am not really to punkin on diggin trenches by hand for the 18x20 run I want to build. Has anyone ever laid out expanded metal on the ground, say 2-3 foot outside, one foot inside, and put the run fencing on top of that? If I staked it down, I can't see how anything would dig a 3-4 foot tunnel to get to the chickies. I might really be missing something there tho. This is a fascinating website, I have so many new ideas to incorporate, I am losing sleep whilst in design mode. I can't imagine the sleep I am about to lose when spring gets here and I actually have to "tend", but I can't wait!
