I have about 26 hens, 1 turkey, 1 duck, & 8 guinnas all living in a large fenced yard... I also have 4 roosters & 3 male ducks penned in.. Everything has a ground floor.. I have LOTS of mice everywhere.. I’ve tried dripping rosemary into the holes, rubbing it on the dishes.. the chickens catch one occasionally... help!! Is there anything I could do that won’t hurt the birds..
