We are also in the north east. Pretty soon I will remove some of the deep bedding in the run. But that is to add to the gardens. The run doesn't need cleaning in our case. That means no smell. Chicken poop gets scratched in every day. We move the coop shavings and poop to the run and because we add leaves and yard waste to the run, over a year it builds up. And this process certainly helps with some great fruits and vegetables. The process goes like this. Fall add compost from the run to gardens. Fall add leaves, pine needles, annual coop clean out to the run. Do that over and over. The veggie garden did quite well this year.
