Does anyone know how to get rid of mice under a coop? My 8 X 12 coop is built on concrete blocks, which leaves emply space under the coop for mice. After the last hen goes in at night the mice come out and party. They climb the sides of the coop, go into the coop through the chicken door and run around the chicken yard. I tried shutting the chicken door and using mice traps outside, but they avoid them completely. I'm afraid to use poison in case a poisoned mouse ends up in the chicken yard. Any suggestions? Oh, and a cat is out of the question since our dog would turn it into a squeak toy and I am not a cat person, anyway.
