It will also matter if you are by one of the big lakes or inland. Humidity is a game changer. It's sometimes hard to beat if the relative humidity outside is just as bad as it is in the coop full of chickens.
I will also say I used vaseline my first year without any relief for my large combed birds. I got advice later to purchase bag balm. Much better. Waxier in the cold. Can repel moisture better. But the BEST way to avoid those issues is hopefully you have the right breed for your climate. (Comb-type)
