Hi Mitch I just saw your coop looking good. I grew up in lake county so I know what you winters are like.I wouldn't add heat to your coop if the girls are raised in the coop they will be just fine with the cold as long as they can get out of the wind. If they get used to heat in the winter and you loose power they won't have time to acclimate to extra cold and if their used to it being 30 degrees and all of sudden it's 10 below the may not do so well. I live in Ky now but my girls don't seem to mind 10 degrees and still want out. Now just a couple of other points.
Chicken wire is worthless for protection from coons, when chickens are scared they will bunch up in a corner and if up against chicken wire the coon will reach in and pull their heads threw the wire and just eat their heads. A 2 foot layer of hardware cloth along the bottom of your run will prevent this
The venting over your nest boxes is pretty much like mine but needs to be covered with wire. I found out the hard way that a hawk can and will crawl threw there.
Don't forget about cats they will take chickens anytime of the day.I live in the country and have all kind of critters fox,coyotes,coons opossums, skunks, hawks and owls but cats have killed more chickens for me than the rest of the combined.
You are doing a great job for your fist coop, way better than I did I"m just trying to save you from learning some of the lessons the hard way like I did.
Good luck and enjoy your girls
