Hey Chelsey, I'm not picking on you, honest! Have you visited on the Maine thread? I'm in Central Maine, and have been avoiding shavings like the plague. IME, shavings do not insulate as well as hay or straw. Shavings are much more apt to create ammonia issues. My preferred bedding is dry leaves, but when they are in short supply, I'll bust open a bale of hay that I've stored in the coop for just that purpose. I like to put 3 bales in and make a tunnel/pyramid for winter entertainment. The hay WITH leaves makes a fair mix, and I'll be honest. I buy mulch hay, and it may already be moldy with a powdery white mold between the flakes, when I break a bale open. No issues in my coop, what so ever.
I've found that experience is a far better teacher than some of the "they say" statements that are continually perpetrated. I take all of the "they say" statements, sift them with a lot of grains of salt, and ask if "what they say" actually makes sensehe Then, I'll play around with it to see if "what they say" is applicable to my situation.
I'm glad you're using deep litter. I've been doing so for 4 years, though my experience with it actually composting on my sheet flooring over plywood floor is variable. I generally do a fall clean out, while leaving some behind, and then build the litter up through the winter and spring. May clean out a bit at end of spring, and let it go again till late fall. I'm pleased with how well it works in the warmer months. Never any odor.
