I am planning to get chicks for the 1st time this spring. I live in St. Paul, MN and it can get very cold here for a couple of months in winter.( Like zero with very low windchills of minus 25). I am trying to figure out a good type of chicken coop. I've read so many different things like: you don't need any kind of heat source, you can have open sided coops, the coop should be sealed and not drafty but have good ventilation, etc. How can you have a non-drafty house but have ventilation too??? Dosen't make sense to me. There are so many different thoughts and ideas, I don't know what to do! Also, I can only have 4 chickens in the city limits. Will this be enough to keep each other warm? I want them healthy, happy, comfortable, and would like eggs. What should I do? Any suggestions? Another question I have. Has anyone had chickens and a rabbit housed together? I'm thinking, one house, more room for the animals. Any thoughts??? Sandy J.
