Hi! So, I started designing my coop/run with a wood floor covered in linoleum. I designed it to be an 8 foot long and 4 foot wide rectangle. Then I changed my idea to a 6 foot square run with a smaller 3 foot square coop inside. If I do the second design I figured I would just have a dirt floor. I would dig down for the hardware cloth to be underground. Now I have the idea of maybe a concrete floor! It seems like the concrete would be SO much easier to clean! How much does concrete cost? In easiness which would be easier: digging maybe almost a foot down or doing concrete? Do raccoons dig underground? Is that why you have to dig and put hardware cloth under? Or is it some other animal that it is for? I think raccoons are the only animal that I need to worry about. I want it to be perfect so I keep on changing my mind!! Thanks so much!!
