I live in the Shuswap of British Columbia. We have horses and dogs on 5 acres and are planning to build a coop this spring and get 6 - 12 chicks. Thinking of getting some Barred Rock and Easter Eggers. Our summers are warm 25 - 35 Celsius and depending on the year our winters get little or quite a bit of snow and temps between 5 - -10 Celsius sometimes a week or so of colder. Do we need to insulate our coop? or is supplying a heat lamp sufficient during cold periods? We want to free range our hens. Do you still let the chickens out in the snow during the day? or should I be building a covered run and not free range in winter? I'm sure I'll have more questions as we go along. Thanks for any suggestions for this beginner.
