I have a coop (lean to style) and I need to add a run to it. I was thinking about adding an A Frame run but I have some questions. With the A Frame style, there is no covered area over the run. The coop/run is located in a very shady area that does not get direct sunlight. So I thought that this style would be fine, since they are already in the shade, they don't need a roof to shade them even more. But, then I was worried about rain. Since there is no covered roof, would the rain bother the chickens? And, if I was planning on putting sand in the run, would it be a bad idea since there was no covered roof? Would the sand just get washed away or something? I'm hoping someone can help me out with these questions. We had planned on building a covered run but the handyman said the material would cost $400 and that's way out of my budget. I'm just looking for something more economical.
