I am currently in the process of reading the below book on Woods Coops. http://gnipsel.com/files/chickens/mfaph.pdf I am considering having one built on my property to house a number of chickens instead of using the plastic sheds I currently have. They have very poor ventilation and I'm thinking I need something different. But anyway, I live in Ontario Canada where winters get pretty rough and temps get cold. In January of last year temps were at around -35 C give or take a few degrees here and there. Some winters have been much worse, some have been better. From what I understand the Woods coop is an open front designed coop. With hardware cloth covering the front. Similar to the below picture. I know that many people have used woods coops in cold places but I am just trying to wrap my head around how having an open front like this in a place where winters get very cold would still be a safe idea for the chickens. I do realize that ventilation is more important than insulation though. I have asked around about drafts given the design and was told that this is where the "air cushion" effect comes in. That the wind causes cold air to enter the front but the cushion does not allow the air to penetrate all the way to the back where the chickens roost. I'm not really sure how this even works but trust the information given to me. But is the Woods style meant for colder regions or is it designed for more warmer ones? Or rather can a Woods coop perform well in colder conditions? Even with this knowledge I am looking to gather the experiences of people who have had or do have Woods styled coops and live in colder areas. Are the chickens fine? Do they get too cold? Would there be a better option given the information I have provided? What do you guys and gals think?
