I currently use a metal feeder which is suspended from the coop roof. At night after chickens go into the enclosed coop area I lift the feeder off the ground with a chain and secure it til morning. The feeder is covered with a dish but the troigh still has food in it. Every morning i still find moise poops in it. Tonight i secured the.feeder within a plastic garbage bag before hanging it. Thoughts? I have traps set outside the coop but so far nothing. Maybe i will find one in the bag in morning
