The fencing next to the coop is enough support for them to get onto, or into the coop.Because only one post holds it the edge of the balcony is 2.5’ minimum from it for the predator to use the hind legs to climb up. I watched videos how raccoon, cats and dogs can climb over and all need vertical support to push up even if they grab the edge with front feet. Also because of the small space between overhang roof and the balcony edge they can not land with all four even if they can jump up. That stops the owls to get there too. Let's say they would get up than they have to tear down the smart siding board, also my chickens have exit door. Because they have the overhang roof and the entrance is so camouflage, they are not on display and no one even tried yet. I had 3 owls coming for three months day and night and they never figured it out. I had a family of the raccoons in the tree what fell on my house and they never figured it out. So what do you think?
