I have noticed at my chicken coop there are a few holes around and I know that its mice holes because I saw a mouse run into one...I tried to set traps out and they didn't get anything..I'm kind of afraid to put poison out because if it gets into the coop and the chickens eat it(I've seen my chickens pull mice apart literally)..or if the mouse dies in the coop I'm afraid that it may hurt the chickens/do something to the eggs they lay possibly? I'm just not sure what to do beyond that point..I have hardware cloth..they are burrowing under somehow..any ideas would be helpful? Thanks
