I've read a few threads on here about the mud issue... and am aware of the "deep liter" method. Which I have been doing but apparently not deep enough. I have seen where some people build a screen type structure that keeps the chickens from getting to the ground (I think it might be called a grass protector). In my mind I'm thinking this is a win-win... keeps them out of the mud, and once grass gets established again it gives them something to snack on. Does anyone have any other thoughts on this...What if I covered the entire floor with it (run is 12'x16')?
