This is a nice little coop and run. The manufacturer claims it can hold more, but you are wise to keep it at two. The stones around the base are a good idea, as is placing it under the partial protection of the stairs. These little coops are great starter set-ups, but do need regular maintenance to keep them sturdy and functional. I HIGHLY recommend a wood treatment each Spring to prolong it's life and a sturdy latch on the lift-up nesting box roof to preserve your chickens'!
