I have just built the main structure of my coop/house. It is 6ftx12ft w/ a large window on one of the short walls, doors on the other short wall. I had planned to make my roosts from branches and place them on the inside (connected to my shed) long wall. With nest boxes on the outside wall. My question is - Is there really a strong advantage to making the next boxes have an outside hinge access? The only logical one I can think of is I would not have to put my chicken boots on to collect eggs... Outside short wall: A two foot human door w/ a 14 in chicken door (unsure where to put my run) The wall on the right (tall side) is the outside of my shed - roosts will go along that close to the window. I am thinking of having 2 sets of 4 nest boxes off the floor w/ storage under them? We will have 20 chickens... excellent egg layers - Barred Rock and Cinnamon Queens. Anyhow, The question is do you you recommend just attaching them to the walls (on the left) or make an outside access to them.
