This is my first winter with my chickens. I got them back in April and now it's starting to become cooler. I live in New England in NH. So winters will become cold and snowy. And most likely we'll be getting snow before thanksgiving. My question is what to do for the hens to protect them when they are out in the run and at night when they are sleeping. I have attached a picture of the coop when we got it all set up back in June. Their food is now hanging and they have a nipple water container.
