I have a pile of dirty pine shavings and all the other gunk that gets mixed in with it from when i clean out my coop in a pile with other weeds and old pumpkins,gourdes, etc as my compost pile. The girls and 'Bird get into it and root around and scatter it all over the place on a daily routine when i let them free range in the late afternoons. My question is, Should I be letting them do this? The pile is 90% soiled shavings, poop, and whatever else they have had on their floor (old scratch, old food, etc.). I am worried that if the old scratch and crumbles in a foot down and they get to it, cant they get sick from it as it would be soured and rancid? Should I fence it off from them? or maybe burn it instead of letting them have access????
