Should I heat my coop? It’s made of cedar and all cracks are caulked. Windows are tight and no drafts can get in. I’m in Missouri where winter might be 60 in the day and 15 at night or 69 one day and -4 the next. I ask because I posted in the emergency formula earlier about a possibly dying or egg bound chicken. Once she came inside and got a warm bath and a snack she seems better (let’s hope it stays that way). Im wondering now if they’re getting too cold though. All my breeds are supposedly cold hardy.
