My coop is too small, now that my flock has jumped from 5 to 9. ( What was I thinking?) If I added another coop at the other end of the run, do you think they'd use it? Or would they just flock into the old coop and push each other around? I am not likely to build my own coop, so I'm considering getting another of the factory made coops that look so big in the pictures and so small in the world.
