I bought rollaway nest boxes that are communal. No dividers just flaps in front of the box and they all pile in and lay eggs. I had an issue with a chicken that would occasionally eat eggs and get others to join her. I love these new nest boxes. In my last coop I had old cement floors so I bought a rubber stall liner for my flooring. When it came time to spring clean I’d just roll it up and drag it out and hose it. With my new coop I put vinyl flooring down and just tacked it. I use sand in my coops and runs.
