I had put some insulation panels on top of a shelf in my pig barn. I moved the panels today and a ton of small mice came running out. I have seem mice in the chicken coop a few times, but nothing like the nest under the panels. I do not leave any pig or chicken feed open. I did use some grass hay for bedding for the pigs. I was thinking of getting a couple of cats or kittens to help catch the mice in the coop and barn. Do cats go after the chickens or chicks? What should I try?
