The original plans from MPC were the single coop. I decided to build my coop on a concrete pad that was already on the
farm. I realized that there was room for more than one coop, so we built 2 side by side and linked them with an isle.
I guess I could have built one, but I was new to the process, and just stuck to the plans. One advantage is that I could have
2 different breeds, if I planned to raise chickens, but I have 2 mixed flocks of egg layers.
