Oh yes! Even the best run made of hardware cloth is not as secure as wood walls. And if your run is just chicken wire, it's definitely not predator proof. Also, leaving the door open could create drafts up by where your chickens roost - and it's not the cold that can make them sick, it's drafts. You need good ventilation above the roosts and a well sealed lower part of the coop, including the door.
