Im looking to add better sand/dirt to my girls coop (around at least half of it to be exact) . I do have a few things though, it has to be something that wont get damaged by rain or become icky (the coop is opened all around so water gets in very easily) . I would like something that wont harm the bugs or creatures under so they can still scratch in there and find things but the ants are bothersome
-they can go and I would be so happy!
If not, just anything good for them that is waterproof that they will enjoy!Any ideas?
