I have a HUGE rat problem in my coop! It has gotten so bad, that I now see rats running for cover in the middle of the afternoon! I don't know what to do! I have tried traps! They just take the bait and squeeze through the bars. I'm afraid that they are going to hurt my chickens! They are really big brown rats that are eating my chicken feed right out of the feeder. HELP! If ANYONE knows what to do, PLEASE respond!!!!!!!!!!
