The easiest way to do this is to ensure that they have an area in their yard for dust baths, even if that means you provide a box with low sides full of sand that is big enough for one or two of them to get into it and flop around. Add some wood ashes to it as well and it can be both treatment and preventative. Keeping your chickens clean and dry is the best way to keep problems from starting. If you see anything unusual, always check it out quickly before bigger problems start!
