I can't imagine putting in that many hours and still having primary responsibility for caring for the animals. You have good lighting in your pens to let you tend them after dark?
I ordered a hat with a built-in LED light since it gets dark so early now. Great Christmas gift idea if any of you are looking for ideas.
Actually, I go to work at noon, so get everything done in the morning, then shower so I'm clean to go to work

I've got clip on LED lights as well as small flashlights I can hold in my mouth. I buy handfuls when they are on sale.
At least this weather saves on water issues, I still have my outdoor house system turned on so don't have to haul as much.
