Backyard Chickens, Compost Bins and Rats
Backyard chickens and compost bins are common on the west side, and both can feed rats if they aren't set up right. OSU Extension has specific advice for each.
The Coop
OSU Extension recommends wrapping coops in welded hardware cloth with quarter-inch openings instead of chicken wire, burying it several inches below ground, and sealing any opening larger than a nickel. Rats dig, so the buried skirt matters as much as the walls.
The Feed
Feed is the real draw. Store it in metal cans with tight lids, don't leave feeders out overnight where rats can reach them, and clean up what the hens kick out. OSU Extension says plainly not to leave chicken feed where rodents can get to it.
The Compost
Use a closed, rat-resistant bin or a hot composting method. OSU Extension notes that even compost without food scraps can draw rats if it isn't hot enough to kill the insects they eat. If your setup isn't rat-proof, keep meat, dairy and bread out of it.
Bird Feeders and Fallen Fruit
Keep bird seed off the ground, use baffles, and hang feeders away from the eaves and fences. Pick up fallen apples, plums and pears too. OSU Extension lists dropped fruit among the foods that draw rats in.
Questions People Ask
Do I have to give up my chickens?
No. It comes down to the coop, the feed and the cleanup. Get those right and the rats have much less reason to visit.
