I have a BIG problem with mice in the coop! The mice are eating all the food, drinking their water, and even sleeping in the coop at night! I have put out poison (where the chickens couldn't get it) and it killed about three of them, but more just came along. They are making me go through so much food and corn scratch, about a bag every two weeks, and I only have 3 bantam chickens. I put up the food (I also have a secure food container) and the water at night, but I do leave out the scraps. I'm just looking for cheap, effective ways to get rid of the majority of them and to also keep them away. I can't get a barn cat and my dog's scent isn't deterring them. Anything will help! Thanks.
