We're going to build a coop & run for 5 chickens (going to get baby chicks to raise once we've got things squared away. Can someone help me figure out how to build a coop, nesting box & run for $100 or less? We want to build it as large as possible but also predator proof. Is a run that is about 8' wide by 16' long a good size? Would it keep them from feeling cramped? How big should the coop be for 5 to fit comfortably? The coop & run will be completely enclosed, top included, so they will be able to leave their coop at will & walk around in the run. Could they be considered free range like this even though they would be in a pen? And would it be ok to let them out for a little bit when we're home & outside to watch them or would they run off? Or would just staying inside the run all the time be ok? Thanks!!! Pictures would be so great & details if you guys can. We're going to be getting 5 girl sex links.
