I’m in Jordan, Ontario, Canada. Yes we can have lots of rain, barely any snow this year and we have our resident red tailed hawks and Cooper’s hawks and owls along with weasels and coyotes. Haven’t seen any coons. Roof....that might be tricky. Maybe 4 T posts with a tarp? Put several of those around the run. I noticed a guy down the road built a really nice enclosure. I’ll have to show my husband. Btw.....I ordered 5 Austrolorps....I hear Orpingtons can be broody and Austrolorps are part Orpington so hopefully will be docile too and lay more?
