How have you done it? I currently have a large family of rats living under my coop. They're starting to wait longer and longer to run under the coop when they see me. We have mouse traps, but my parents say those won't be big enough. Poison is an option because I have a place in the coop where the ducks couldn't get it. So, advice, please. Should I buy some rat traps? Or will the mouse traps work? And what is your opinion of poison?
