Mine don't have too much trouble with the snow. They will walk in it without a problem. They love to eat it. One thing with snow is making sure they can get up out of it every so often so they can roost and warm their feet against their bodies. I throw lots of lettuce and greens in the snow so they get used to it, and will excercise a little bit instead of staying in the coop. If it is going to snow really heavily, or the winds are going to be crazy, I will hang a tarp on the West side of their run to block the worst of it.
