Dude, that is one down in the dumps buckeye!!!!!
If he has mites to the point of effecting him this badly you would be able to see the eggs/parents/a mite block party at the base of the feathers around his vent. His condition looks alot more serious than just a bad case of mites. To battle mites year round I took the largest rubber tub I could find at the feed store, and placed it in the coop. Put a bag of top soil, some sand and a generous helping of DE, my chickens dust themselves all year long and in turn they keep themselves mite free!!
It could be worms, I feed mine DE in their food, I don't know how else to treat for worms.
Does he gurgle or makes a raspy, whistly sound when he breathes? The high humidity in the winter typically causes more problems than the cold.
In the winter we need to keep the snow and wind off of the birds, but ventilation is a must. An old wives tale in our area is "if you have sick chickens tear out a wall".
I would bring him into the garage in a dry secluded well ventilated cage, put some apple cider vinegar in his water, give him a tray with Black Oil Sunflower Seed, chicken food, cat food, table scraps including small chunks of meat, etc., if his head starts to turn upside down it may be too late. If he does not improve in the next 2-3 days you will most probably lose him, plain and simple. If you want to keep him, you may want to call your local vet.
