My cute little coops have arrived. They are just waiting for me to fix them up, build a run, and most importantly, add some chickens! Question: They are up off the ground which I like for dampness, mold, etc. We plan to build the run even with the front of both buildings and off the back sides so the back of the coops will be in the run but the front and sides will not. I know I need to block off the opening on the front and sides so varmints can't get in there. Should I leave it open in the back for shade, shelter, etc. I'm so excited to become a chick mom!
