I tried to hot compost the shavings from coop...had to add a ton of water and it jumped to 160F. I didn't keep it 'managed' and the shavings never really broke down even a bit, tho the nearby trees sent a plethora of tiny roots up into it. Am going to toss it out into the deep litter in run this year.Aart, thanks for the clarifying answer to my question before I asked it. I was beginning to get confused. My plan is to use the deep bedding with pine shavings in the coop and am adding a large clean out door on the north side, easy access to the compost bin. That door will be blocked during the winter with straw bales to help protect the coop from the north winds.
You really don't want to mix not totally rotted wood into your garden soil, it eats/soaks up the nitrogen, stealing it from your plants.
Does work fine on the surface as mulch tho.
