I live in South East Michigan. I have six chickens, 2 silver laced wyandottes, 1 buff orpington, 2 easter eggers, 1 silkie rooster.
Winter will be here before I know it and it got me thinking about how they are all going to stay warm enough in the winter.
Do I need to put a heat lamp in their hen house? A regular light bulb in the heat lamp? Do they need anything at all?
Also, what is the proper way to vent the coop in the winter?
Here are some pics of the run and coop (the chickens pictured are now full grown):
