I know some people use DE as a dust bath material, and I was thinking of putting a little bin in my coop with something in it that would NOT get rained on and muddy. They have been walking around in mud for the last week in the run, we are working on adding more sand (dirt has a lot of clay in it and it just turns into squishy mud!!!) So with the run wet/damp, they cannot dust bathe unless I build them one in their coop. I was thinking a low pan of some sort with DE or Stall-Dri in it. Didn't want to make it too "private" or someone may start laying eggs in there. What do you guys think?
