It's why backyard chicken owners often set up a dust bath station right inside the coop. Dust baths help birds work grit down into their plumage to absorb excess oil, dislodge parasites, and keep their feathers from getting matted — something a wet bath can't do by itself. It's a small feature that can make a big difference in attracting the types of birds you want in your yard. So, in addition to making a DIY bird bath, consider setting up a dust bath as well. For the waterproof container, make sure it's shallow, as the low profile will make it safer for the birds.
