Sorry if I wasn't clear Perris. I did say the coop was designed for England. If you use it in combination with a good run or free range whole year round its probably fine.you misunderstand the type of coop in question; this style is designed just for sleeping and laying in. My birds use these coops - and in preference to a wooden one which sits empty unless I use it as a hospital coop.
I was refering to people in the US. I think any small coop is not fit for winters with lots of snow and temps bellow freezing for a long period.
2 years ago we had about 10 days with freezing cold and snow in the Netherlands. The chickens didn’t want to go outside. And I really felt sorry for them staying in a coop/with covered run size of about 2,5m2. I now this is a real problen in many area’s in the US and if course in Canada too.
If we had such cold for a month every winter I would probably choose to buy a shed or build a bigger coop for my chickens.
