I had ZERO idea of where to put this... We have a HUGE rat population next to our chicken coop and we just can't seem to keep them out. It's becoming a bit of a problem with our birds and we don't want to kill them... Any advice on how to drive them a bit away.? We don't mind them hanging around but the population is rapidly growing and I saw a very large male in front of our coop, he was about the size of a wild bunny so that alone is a bit concerning for the birds. So basically- is there a humane way to drive them a bit away.?
