How to Keep Rats Out of Chicken Feed (What Actually Works)

Rats do not show up because you keep chickens. They show up because you serve dinner every night and leave the buffet open. Once established, a rat colony is hard to evict, so the goal is to never make your coop worth their time. Here is what actually works, and what only sounds like it works.

What works

Remove the food source at night. Rats forage after dark. If feed is gone or sealed by dusk, your coop stops being a destination. Either bring feeders in every evening (works, but you have to do it forever) or use a treadle feeder that only opens under a hen's weight.

Metal storage. Rats chew through plastic bins and feed bags in a night. Galvanized metal cans with tight lids are the standard for a reason.

Clean up spills. Scattered feed under the feeder is a nightly rat magnet. No-waste feeder designs and a quick evening sweep remove it.

Close the coop itself. Rats also come for eggs, chicks and warmth. A coop door that reliably closes at dusk, and hardware cloth over every gap wider than half an inch, keeps them out of the building.

What does not work as well as people hope

Cats: some are ratters, most negotiate a truce. Ultrasonic repellers: rats habituate within days. Poison: dangerous around chickens, children and owls, and it kills the predators that would otherwise handle your rats for free. Fix the food supply first; in most backyards that alone solves it.

The order to do things

First, seal feed in metal. Second, stop the overnight buffet with a treadle feeder or nightly removal. Third, close the coop at dusk, every day, automatically if you are honest about your own consistency. Fourth, only then think about traps for the stragglers.

Step three is the one keepers skip most. Our automatic coop door closes on schedule every evening, with or without you.
