My wife went out to one of the chicken coops last night to check on everything before going to bed. She came back to my office with a light and a BB gun wanting me to go on a rat hunt. We have had no problems with rats until the weather turned off cool and at night they are going in the coops and eating spilt feed. Got 5 out of 5.(I only got 4 and my cat got 1) Will have to try again in another night or two.
