I'm building my first coop and am using 2x2s for roosts. There are four roosts, each 48" long with a distance of 10 1/2" between them. There is a distance of 9.5 inches from the bottom surface of the 2x2s down to the droppings board. I want to use some hex mesh chicken wire as a barrier to keep the hens away from the droppings board. Is it ok to secure the wire to the bottom surface of the 2x2 roost or should there be a greater distance for some reason? TIA, Der Alte Since I'm an Engineer making a chicken coop, does that make me a Chickeneer?
