I have been studying this site for a while. Also, studying a lot of the links that many of you have posted (love it). This is a lot more informative than the books I have. This is my first post. I have drawn very amateur plans and I would like some opinions. My DH is not a great fan of the (chicken idea) but I think he likes it better than the (move and buy a cow idea). He hates to be limited by all the animals when he wants to go somewhere. His only viable objection would be the initial cost. So.....I have been searching craig's list and I have found some 24"x24" squares of one inch thick plywood. I was so excited. The drawback is that they each have a 6" round hole in the middle. The plus was the guy had hundreds of them at 20 cents each. As I pondered how I could use them I decided that the holes could make great added ventilation. My plan is to cover each hole with an 8" square of the same or thinner plywood. The ones on the top row will have hardware cloth covered by a hinged flap of plywood so it can be closed as needed in the winter. The bottom 2-3 rows may also have the squares placed on the inside of the coop with insulation added between. The windows will be hardware cloth. Will add plexiglass in winter as needed. Some winters in Tennessee are colder than others. The floor will be dirt (which leads to other questions for the dirt floor/deep litter method folks). I want a pop door on either side but with the squares situation I am not sure what to do. Do chickens care about the size of the pop door? The run will be large and probably divided in two. I drew the holes and little squares on the front but not sides of the plans. Also thought it would be cute to have the coop one color and the little squares another. Thanks for any input you folks have.
