I live in a very humid climate and have to get rid of moldy organic crumbles periodically. I thought this stuff would be ok in my compost piles (I keep one outside the hen yard and two inside and put stuff I do not want them to eat in the outside one. Maybe once a year I toss the finished compost into the hen yard so the girls can enjoy the bugs before the compost goes to the garden. This has worked fine, but I recently dumped a bunch of moldy crumbles in my outer pile and it went all stinky on me. I piled grass clippings and leaves on it and am hoping for the best. Does anybody have experience composting old chicken feed? Did it work? Is the end result useable? I hope for the voices of experience! Thanks all!
