I like in coastal Virginia, right near the Chesapeake Bay. I've never had chickens before but I am looking forward to it big time. I've been reading tons of posts over the past couple months, and am in the process of designing my coop for 4-6 laying hens. I have noticed a couple mentions of removable walls, and also some suggestions for using Plexiglas high on the walls, near the eves, to give extra light. I have considered merging those two into a removable Plexiglas wall. Instead of having a solid wall w/panes of Plexiglas in it, I was thinking Plexiglas sheet however many feet in size as the wall, with opaque bits attached to it. Not sure how much to leave clear. I was thinking sturdy wire, possibly 2 overlying layers, that would be the "wall" when the plexiglass wall was removed in the warmer months. I figured having lots of light would help them lay in the cooler months, any suggestions?
