I live in central minnesota, evertything I have read for those of you more experienced with chickens than me tells me not to heat my coop unless the chickens "tell me" they are cold. So what about the eggs, I don't collect them until I get home at night... about 5pm. Most of my chickens lay before 12 or so, but I have one that doesn't lay until around 3.. Do I have to get someone to come in and collect the eggs earlier than 5??
