Don't follow my practices, however, I leave my coop open. My hens freerange but I have a coop and run that I can move around. But unless we have a loss, we leave everything open. We have had 2 early morning killings lately, so we are shutting the run door, at dusk or just before and opening it up about 8am so the danager has passed. No more dead hens. We have also put out the Humane trap and the leg traps and baited them and whatever it was that was getting the hens - managed to avoid 2 hidden leg traps getting in and out of the run, with the dead chicken we retrieved - hopefully the rat posion will get it.
