Hi everyone! So far we have built a secure 8' by 10' run with a plastic corrugated roof and are planning to build a 3 1/2' by 3 1/2' coop inside. We are thinking of making it easy to clean by having the walls removable. In addition, we may end up moving the coop outside the run and enlarging it at some point, so we are reluctant to build a permanent coop inside the run. Our question is : is it common to build a coop that disassembles for cleaning as well as for moving later on? Keep in mind that the door to the run is only 3 feet wide, so if we build something permanent inside of the run, it would be stuck there. THANKS FOR THE HELP!
