We are getting ready to start on our coop and run. Should we use concrete blocks under our coop and run base/frame? And why or why not? I'm sorry if this question has already been asked. I look through the forums and didn't see anything about using the concrete blocks. If it has been posted please direct me to the thread. I have noticed on some of the coop pictures that people dig an area out and put the concrete blocks in then put the base/frame on the blocks. Is it for predators or more for better construction? Thank you!
