My temps are similar to OP. I use DL in both coop and winter run. When I clean the bedding from under the perches, it gets scooped out into their summer run. I add extra material to the winter run, in an effort to keep the DL a minimum of 6" deep. Old hay, leaves, wood chips, garden debris, grass clippings. The run is partially covered with a green house tarp (over one section of the roof) and the remainder of the roof is covered with 2 x 4 welded wire to keep hawks out. Yes, they even visit in the very late fall, early spring. No doubt raptors also visit in the dead of winter. The 3 sides of the winter run are covered with plastic to provide a nice "green house" climate. Usually 20*F warmer than ambient temps during the day. The girls happily create compost for me all year round.
I will never consider sand as bedding material anywhere, after visiting a friend who uses sand for both pigeons and chickens. He meticulously rakes poo on a daily basis. Yet, 5 minutes in his aviary was enough to send my asthma into overdrive for the remainder of the day. Stink? Yeah. On the other hand, DL done correctly does not need maintenance other than adding more litter. I can also harvest wheel barrow loads of rich black compost from the run for my gardening pleasure.
