You don't have to be much of a cat person to adopt a feral barn cat (adult instead of a kitten.) You would provide a cat house/shelter next to your coop and feed them daily. There are 3 levels of Feral. You don't have to worry about cats getting to chicks as they would not be inside your coop. I built a cat shelter that is a "bump out," of my coop and it works great. Look up your local Feral Cat society and fill out the barn cat form. I got rid of my rat problem, predator proofed my coop and then adopted 2 feral cats. They for sure do the job of keeping rodents away (they are the control point of the getting rid of rodents project.)
