Last year my wife decided she wanted chickens so I found this site and did a lot of reading about them and building a coop. After all said and done I had about $1000.00 into her setup and chickens. My wife was very happy. After about six months we started noticing holes in the ground in and around her coop, I set out my trail cameras and found what was making the holes was rats. They even moved into my garage a few feet away from the coop. After a few months of trapping them and putting out poison I admitted defeat and sold everything. So here is my warning to all if you live in an area where there is a possibility of rats don't get chickens if you don't want rats.
