If you post your general location on your profile, you'll get recommendations based on your locale. If 5 (F or C?) is your low, your birds likely won't need heat over the winter. Your bigger concern will be protection from wind and drafts without compromising air circulation - which isn't as impossible as it sounds ... honest!Love it! Yea - I was hooked the first time I saw chickens in tractor supply. Been wanting to do this for years. I was gonna wait until this spring until I saw that I could pick the date for when the chicks would come in the mail. They will be adults in December so I’ll have laying hens in the spring rather than waiting all summer. Now how to keep them safe through the winter. Open to suggestions. Jan will have us down to 5 degrees for a few days.
