This is great! My original plan was a fresh-air coop, dirt floor, and fenced "run" (actually a 30'x20' area) with out screening on top. After researching and learning about predators I starting planning a closed coop that I'd have to open and close a door twice a day and a fully fenced run (25'x4' with screen on sides and top). It made my heart sink, as I just can't believe the birds would be healthier or less stressed like this. Also, I'm not guaranteed to get to the door open and close on time, so now I had to plan a fully secure run as well. . . . At this point I doubted chickens were for me!
So my question: do you have a fresh-air coop that is still screened and "safe" or do you use an electric fence or ??? Do you have a dirt floor--love this idea for beneficial microbes and a deep litter system that could go into the garden once a year. Also, what about a run? Would love to hear from another advocate of the fresh air system and what they're doing.
