I have them for convenience. Through the week, I am up and gone. Before the sun is even opening and rubbing it’s eyes. We also have other animals, so with the automatic doors. There is one less thing on my to do list, before I leave for the day. I am not that concerned with security. Since the pop doors only allow access from the coops to the runs. Which are well built and secure against most predators. The bear population in my area is growing. So I need to build an electric fence around my chickens area. Which will hopefully deter them from destroying my facilities.
