This probably isn't considered an emergency, but I wasn't sure where else to post this. With the freezing weather that is coming our way, starting tomorrow, I'm concerned about our chickens. We live in Georgia and typically we don't see many nights below 15 degrees. However, the weather is calling for the temps. to start dropping tomorrow and be around 5 degrees Monday morning. Are there any things I can do to help my chickens stay warm enough? I just want to make sure they don't freeze. They are in a shed/coop, so they have shelter from the wind. We have 20 chickens, so I'm hoping their body heat helps. Any suggestions? Thanks!
