Just a reminder to keep light bulbs in the coop dust free! I had one of my heat lamps shut off for several days and then with this cold snap plugged it back in. I was surprised at how much dust collects and it had a "just turned the electric heat on" smell to it. My inlaws lost a coop of chickens many years ago and they think dust build up was the culprit! It will be nice when spring comes and I can give the whole building a good cleaning! Dusty little critters!
