Chickens are generally clean animals and clean themselves in dry soil to scrape insects off their feathers. When chickens peck themselves, they are removing any dirt or insects to keep themselves clean. However, you can bath a chicken maybe once every 4/5 months just to make the chickens feel cared for. It won't clean them effectively as the moisture can make the dirt wet and stick to the chicken's skin.
