My gf and I currently have 14 chicks. We are getting another 30 next week via delivery. We have probably 4 weeks before we have to move the chickens out. Due to the layout of my back yard I am wanting to have a 20x20x8 run/coop. We are utilizing our shed for this, but the materials to build a run is approximately the same as building one(including my time). I am here asking for tips to minimize my expense cause I am a frugal guy, and want to save my money for more chickens. I am also looking for affordable, pre-built options as well. Many thanks in advance.
