Well the coops just about finished, and the coop is predator proof no cracks are the doors have locks and so on, the floor is 1 inch plywood with concrete board on top so no predators can get in. Completely safe. So if they are locked away at night why does the run have to be so secure? I was just going to use chicken wire, but will they still be safe? Have you guys ever had a predator attack during the day?
