How Do I Keep Rats Out of My Chicken Feed?
The single most effective step is removing feed from the coop and run every evening before dark. According to UC ANR's Integrated Pest Management program, rats are primarily nocturnal feeders, and eliminating overnight food access reduces rat activity around poultry areas by a significant margin.
Rats are a fact of life in Santa Cruz County. The combination of mild weather, nearby wild areas, and accessible food makes backyard chicken setups a magnet for Norway rats and roof rats. I deal with this in my Boulder Creek run constantly, and I have found that no single trick solves the problem. It takes a layered approach.
Start with feed storage. Keep all feed in metal containers with tight-fitting lids. Plastic bins, even heavy-duty ones, will eventually get chewed through. A metal trash can with a bungee cord across the lid works well and costs very little. Store it in a shed or garage rather than next to the coop.
Next, look at your feeder design. Treadle feeders (the kind that open when a chicken steps on a plate) are effective at keeping rats out during the day. They are an investment, usually $50 to $100, but they pay for themselves in reduced feed waste. If you use an open feeder, only put out what your flock will eat in a few hours, and bring it inside at dusk.
Your run construction matters too. Hardware cloth with 1/2-inch openings will keep rats from entering through the walls. Bury the cloth at least 12 inches below ground level or bend it outward in an L-shape along the base to prevent digging. Chicken wire does not stop rats. They chew through it easily.
Avoid poison bait stations near your flock. UC Davis Veterinary Medicine warns that secondary poisoning (when a chicken eats a poisoned rat or contaminated droppings) is a real risk. Snap traps placed in secured bait stations that chickens cannot access are a safer option. Place them along walls and known rat paths, which you can identify by the dark grease marks rats leave along their regular routes.
This week: Switch to bringing your feeder inside every evening at dusk, and move your feed storage into a metal container if it is not in one already.
