I do nothing special. I close the windows on cold days which here is most of the winter. I have lots of ventilation up high so it works for me. I use small water dishes so taking hot water out to thaw them in the morning and again in the afternoon works as well. I had the heated water dishes and they failed miserably as well as being expensive. I am thinking about a tank heater for mine this winter since my numbers are up by a lot.
I shovel my run out if we get a heavy snow. The run is to large for me to reasonably put a roof on it.
Looks like I quoted the wrong post, sorry.
You should be fine. Chickens will happily walk on snow, but they won't be happy if there's no place outside for them to peck...they'll simply get bored and stay indoors. So, I would suggest you do what you can to put some portion of roof that will keep snow off the ground...doesn't need to be the whole thing. If you notice, many coop designs leave a space under the nesting box, and uses the nesting box as a roof...voila. If that's not possible, then can you put a piece of plywood on a steep angle next too the coop? Like you, my run is merely covered in mesh, but I have 42' of roofed runs as well as the outdoor fenced area.
