A number of people have asked me, why can't you build a predator poof coop? After thinking about it, I guess you can. But the cost would be outrageous. Think about it, your house is not even predator proof, So why should your chicken coop be? Here is what I came up with for a predator proof coop. Find 1/2 " steel plate in the size of your coop, place this on the 2' cement floor. You will have to cut 1/4" slats where you want a window and put the glass on the inside. The door will need to be beveled like the door on a safe, opening out. Most likely you will need a good combination lock like those on a safe. (To keep the human predators out.) As you can see this type of a coop would be predator proof, but also put a BIG dent in your back account. You can only do so much to keep your criiters safe, as you would to keep your family safe. Believe it or not most chicken coops are as safe or safer than our houses. After that is in God's hands.
