I prefer un-attached individual nests that rest on the floor, especially if I intend to let my hens hatch their own eggs. This way I can move the entire nest to a quite pen or coop without disturbing the setting hen. The reason for high nests is to make it easier on you to gather the eggs, not to encourage hens to lay in penthouse nests.Aart--Thank You! I'm going to have to change my coop design because my nesting boxes are about the same height as my roost. That's what I get for assuming the guy that built my coop knew what he was doing! Lol. Thank you for the great advice!
