I think I have a rat problem!!! I converted one of the stalls in the barn as my coop. I had reinforced everything but not thinking that a rat could get in from the upstairs of the barn into the ceiling of the coop. So, I will be reinforcing that especially the area they might be getting in. Something had gotten a 1 month old chick and I only found the head. I am furious!!! The only thing I can think of that could get in would be rats. So, how can I get rid of these critters without harming the chickens? The chickens could get into a trap or poison. The chickens do have free run in the barn during the day and they do go upstairs too. Any ideas on ways to get rid of them without hurting the chickens???
