Yeah winter is probably a good time to do your chipdrops before the temps warm up and composting accelerates. I put most my load spread out in the run over the first few days so it wasn’t tremendously deep and had a chance to dry out. If you let that huge, moist pile sit too long that core gets very hot. I had the bottom of my pile getting a little moldy, but it had a lot of fines and pine needles too.
