I just found out that having chickens is permitted in my area, so now I am ready to start planning. I have in mind a fixed coop (not a tractor) and a 10x10 enclosed run to protect from predators. I plan to start with 2-3 birds. I've identified a spot that is a mix of shade and sun, and some small part of the run will be shaded at any given time of day. It is also well-drained but there is a slope to the site, about 1 inch/foot. Should I think about leveling the site before building the run? It's not construction issues that I'm thinking about here, but rather issues related to keeping a good run. Does anybody have any experience (good or bad) with using sloped runs that might help me to know if I should plan on excavation before construction? Thanks!
