I live near a drainage ditch and also a large field. The mice in the area have all moved into my henhouse, and night time in that henhouse has turned into a popular mouse hangout. I can't just pull up the food at night, because it is often noon or later before my wife or I can get out to the henhouse the next day. The chickens can't go without food that long. What can we do to get this mouse problem under control? Do they make rodent proof feeders for chickens? Thanks in advance for your help.
