Hey I think I'm in way over my head here! My chickens were wonderful in the summer healthy ,layed well...this is our first winter with them. We are in Southern Ontario and like everywhere it has been extremely cold (-30C). Our chickens are Barred Rock and Road Island Reds. There coop was a wood shed we converted. We have hay in there as bedding and stacked along one wall..there is no insulation but we do have a red heating lamp hanging from the ceiling. Some have had frost bite and I think they are starting to eat there eggs. They haven't left the coop ALL winter. We had a few ice storms so the small door has been unusable and in Dec/Jan we had so many storms and bad weather they wouldnt come out and I would leave the main door shut. So on the few nice days we have had (-10,-15) they stick there heads out the door and turn around. I didn't think anything of it at first but now some are not looking so great. I think they are pecking at each other. We are only getting around 3-4 eggs a day now from the 12 chickens. I think I may have ruined my chickens. Any advice would be greatly appreciated.
