I live in Northern WI. In the sticks. We have 20 acres of woods and a small pond on the property. My husband and I are talking about getting chickens and building a coop next summer. When I told my parents our idea they thought it was nuts and said we would have rats if we have chickens. We already have a huge mouse problem and I would prefer to not have rats also. What are you thoughts about this, and is there any tips to decrease the likelihood of rats? Thank you!
