For future reference, one of the best things to do to prepare for winter is to make sure that your flock is as healthy as they can possibly be. We deworm the flock in the fall, and periodically we give vitamin supplements, oregano oil, Denagard, as preventatives throughout the year, just to try to make sure they are healthy as possible. If the birds have anything like worms or cocci going into the cold winter months, they are going to have a rough time. While our flock is confined to the barn because of cold and snow, I try to make sure they have things to keep them cheerful and their minds off the cold. A visit with a handful or two of snacks in the afternoon tossed out for them to scratch for, or apple or cabbage or corn cob on a string...maybe a couple of flakes of hay or straw to tear apart, some fresh dirt in their dust bath, warm water in their waterers, fresh material for the nest boxes, or a flock block to peck at. Simple things, but they're easy to please, and they seem grateful for even the smallest things. If it's subzero I sometimes leave a heat light or two on during the day for them to get under...I know they don't need it, but especially our peafowl appreciate it. There are heaters available called "sweeter heaters" that are designed for poultry, but really, like has been said before, they don't need it. TLC works as well as anything, imo.
