Hi, I need to get a chicken coop up soon and I have some questions. My plan was to build a coop using pallets but then I came across a large metal shed at lowe's for under $300. I know nothing about the do's and dont's of chicken coops, so I am not sure what to do! I have heard they need good ventilation but no drafts - I don't really understand what that means! I live in Oklahoma so we get some rainy/windy cold in the winters and last summer was 105+ for many days. Would the metal shed get too hot? How would I modify it to make it more suitable as a coop? As for pallets, I have seen a few designs where the slats in the pallets are left open. Wouldn't that be too drafty? So, what would you choose, pallets or the metal shed? Any designs or ideas on how to build/modify either would be wonderful. Also, I have searched for coop designs and almost all of them are small and low to the ground.(not walk in) is there a reason why this is preferred over a large walk in coop?
