I have an enclosed front porch. It's practically another room. I had 4 brooders with heat lamps on them till the chicks where feathered. Then they went out in the grow pen which also had heat lamps. I burned alot of electricity last winter and don't plan to do it again this winter. Luckily we had a mild winter. If we had had an ice storm and our electric went out I would have lost nearly all of them. Thats what we get here in a bad winter. The ice takes out trees and power lines. Last one we had DH stood outside all night during the storm and watched out for our animals. The worst that happened is a tree got so heavy with ice it bend over the coop and pulled out the cord for their light. Although we lost electricity for 5 days and we had to chip our way into the coop everybody inside was just fine. We didn't have any babies to worry about that winter so all I had to do was keep out chihuahua warm. She stayed under my coat most of the time. Except to eat and potty of course. I even slept with her.
