how do you rid your coop of mouses and rats that have come in for protection from the cold? I've tried mouse traps, and caught three mice, but I think my chickens have found where I've hidden them and are setting them off and eating the cheese. Just in case it's really a rat getting into my mouse traps I'm afraid of setting rat traps as I'm afraid they would hurt the chickens. I'm not sure arbout poison as the chickens could possibly get into it, or try to eat the critter that died from eating it. any suggestions?
