right now we have a chicken coop that is wheelbarrow-like so it is able to be moved around. attached is a small run. we loved the fact that we can move it around so the grass doesn't die plus the chickens get fresh/clean grass to graze in. since we had six chickens in that small run, we decided to expand it so they would have a larger area to use when there locked in. we created a wire fence around it so the coop and attached run were surrounded by a larger run. however the chickens began flying out so we had to lay a net thing down across the entire thing. now its a pain in the butt to clean, feed, water, and let the chickens out house because you now have to bend over. PLUS we are now eye level to the rooster (kind of scary since he is aggressive) the other downside is that the fence we made was by using stakes that were driven into the ground AKA its not portable. so now we cant move the darn thing. i was wondering if anyone who had a similar coop was able to create an expansion that was portable and that you can stand up in.
