I have been keeping chickens for 12 years now and I am amazed at how many rats have made themselves at home around my chicken coop and run. I have tried poison in the surrounding area, spring loaded rat traps, have-a-heart traps, electrocution traps and the ones that go on top of a bucket that flips and drops them in. I have used the feeders that open when the chicken steps on the peddle hoping they would leave if I took away their food source. I have even tried the rat repellent packets with mint scent. Nothing seems to work!
Please let me know if any one has any success getting rid of these varmints.
