I live in Northern Michigan and our winters are really hard- about 100 inches or more in snow fall. We basically have 3-4 feet of snow on the ground from December to March (sometimes April). Currently we have 10 chicks- but next spring I will let some ladies brood and I want to grow the flock to about 25 ish in the next 2 years. So my questions- what size coop should I build to make sure they are happy and clean this winter? I have to plan now for this and I also want to make sure it will expand and house my wanted flock as well.... Ideas? Images? Thanks!
