We have a pretty big coop/run setup (see pic) for our 16 chickens. After reading this and that here and there, I thought that deep litter might be a good option for me because I have a garden, and I thought it might help keep the chickens more warm in winter. I live in the Berkshire foothills of Western Massachusets, so we are below freezing most of the winter, and can get 5-10 degrees below zero on occasion. I put whatever in there... there's pine shavings, straw and fallen leaves from the yard. It's about 7 inches deep, and I turn it with a pitchfork every other day or so. We had a very dry summer and fall and it seemed to be looking great. But the past few days have been very damp, and it's starting to smell ammonia-y. Is that a sign that something has gone wrong? Am I dreaming that the composting litter will help create warmth in the coop? Is my coop too big to keep the chickens warm? I don't mind giving up on the deep litter- it's not hard to switch out the litter every other week. A lot of questions, I know!
