Hello everyone,
This will be my first winter with the girls. I have 3 Red Sex Links. During the summer we have been using wood chips in the coop and sand in the run (see below). It has worked very well. However, I worry that those materials won't be warm enough for temps in the teens and bitter wind chills. I don't plan to use a heat lamp as so many on this site have advised against it. I would like some guidance though. Please look at the pictures and offer your suggestions!

Generally there is more litter than shown here. The girls do not use the roost bars at all. They tend to snuggle down in the chips together. All food and water is kept in the run, outside the coop. I think ventilation issues are under control. The litter makes daily cleaning a breeze. If you use straw, how often do you clean it?

The west side and top of the run is covered by a tarp to block wind and rain. Planning to block the short north side this winter.
Thanks for your help!
