Blooie, oh my dear friend! You seriously think that's gonna stop a mouse? They are incredible burrowers. How deep does your skirt go? No, I'm not asking about your pretty pink gingham one... Mice will tunnel right under a skirt. My mother, who hated mice almost as much as she hated snakes and flies, complained that a mouse could back up to a solid wall and squeeze through his pucker hole (to the other side of the wall). That about sums it up. You might invest some time and effort in getting some chicken proof mouse traps. Perhaps try the water bucket/spinning can with peanut butter, with a chicken excluder over the top. Or snap or bear paw traps in a chicken proof box??? There's also an electronic zapper box. Mouse completes the circuit, and gets enough of a jolt to stop all future escapades. With Ken's electronic background, he might enjoy this one! Switch to fermented feed if you haven't, cover the feeder or put it in a metal trash can every night??? Maybe you need to get a cat? But... that comes with it's own set of issues. My cat is not a great hunter, but lately, he takes great pleasure in chasing chickens, just to see them run! Yesterday, he was in chicken torture mode, and Jack came along, and just stood there and gave the cat the stink eye. I was seriously hoping that roo would flog that cat, just a little bit. But the stand off ended in a stale mate! Perhaps you need to invest in a flock of Buckeyes. I've heard that they make wonderful mousers.
