Hi, I've been a lurker for quite a while as I research my chicken endeavor. My Mr and I are getting down to the nitty-gritty design process for the coop, and I'm looking for a bit of clarity - I'm trying to determine the definition of "coop". In terms of sqft per bird, a coop is the weather-proof, safe and secure space they have access to 24/7. Correct? What Ii'm thinking is - If I included a section of the coop that was covered, solid about for about 3' off the ground and wired up to the roof, I can include it in my calculations - provided they can get to it 24/7. Thoughts?
