Right now there is no easy way to load up old straw bedding and cart it out of the coop to a compost pile. The snow is too deep and the weather just wont allow it. We use the deep litter method of just adding more bedding til spring and raking up small piles. Dander dust and cobwebs are really mounting on every surface within the coop. It helps to use a wisk broom and a homemade feather duster to do a little cleanup on surfaces that start to get piled with dust and the like. If you have light bulbs of any sort and or electrical boxes, makes sure you wipe and clean them free of cobwebs and dust. You surely dont want the possible means of a fire starting. Spread a little diatamaceous earth on the coop floor during winter months to help soak up droppings and freshen it up a bit. In the spring, every thing will come out of the coop, including the chickens, and it will get a good hosing down and wash out with some products to disinfect and kill any mites, lice and what have you. I have a dirt floor, so I will add some fresh river sand once it is raked out and all the old and matted straw is removed. Add that to your to do list!
