With a 20 below wind chill. I'm glad I'm home all day to keep an eye on my girls. It's generally pretty cold here, but this morning is a doozy. It's only supposed to hit 4 degrees today. I took a big bowl of warm oatmeal out to them first thing this morning and I'll keep changing out their frozen water throughout the day. I feel bad for them and I'm trying not to break down and heat the coop. I know there are people who keep chickens in way colder weather than this. Hopefully the whole winter isn't going to be like this!
