rnorris,
I'm sorry about that, dang weather. I just bought another heat bulb and I'm heading out to put it in my building for my Serama's and Araucana's. I only have 4 young ones out there and they're fully feathered and doing fine in the cold. I do have a couple of Araucana's in the house that are not feathered yet and a week old Serama chick and 3 pipped and trying to zip out plus a dozen in the incubator. With this COLD weather, I may have to set up an area above the garage that is heated cause my babies are not going out in this stuff.
I keep 2 lights at once so if one goes out, the other on is the back up. I'm considering getting another battery back up, like I have my computer on so if the power goes out my computer will run for a few hours. I have my incubator plugged in to it and I'd unplug my computer in a heart beat if the power went down a while. It also protects from surges. My only concern is that a couple of heat lamps will suck the power down so fast it wouldn't be worth the effort.
What does everyone else do to keep their birds warm?
