I'm getting close to finishing the interior of the coop. I have installed a vinyl remnant from a carpet store on the floor and we will install windows, popdoor and eggdoors on the weekend. Before I start putting in all the other stuff (nestboxes, roosts) I wonder if I should do something to the walls. They are studs with T111 now. I wonder if this white hardboard (4x8ft, 1/8" thick): would give a nice washable interior surface. It would also reflect some more light and it would save me the hassle of having to prime and paint. Any reason I should not do this? TIA.
