It is just getting to dusty in the house for the chicks. They are almost 5 weeks and was thinking on moving them to the coop. The coop is attached to a heated barn. There is a window from the barn to the coop. When I open the window the heat doesn't move into the coop. I have a small fan that will warm the coop right up. My question is will the moving warm air be to hard on the chicks? I will also install a heat lamp but alone the lamp doesn't warm the coop up. What are your thoughts. Don't want to kill them off now by making the wrong decision. John
