Cover w/ other, different sized materials & toss scratch, feed or treats in it. The chickens will LOVE the game of "get it" & their scratching will mix dry material w/ wet. Prevents stinky slime & takes away slippery-ness for persons caring for chickens.as wonderful as dry leaves in the run are…..the opposite is true of Wet leaves. utterly useless!
Just pine needles by themselvesves are slippery, too. Been there, hit the ground hard. Swear the "hennys" were laughing!
