If I want to paint the walls inside the coop, what sort of paint should I use? I get that glossier is better for washability but is plain old interior latex going to be durable enough? Should I use an exterior grade? If it makes any difference, the coop is uninsulated and will be painted on the outside. AND, is there any reason I shouldn't then let the kids paint something cute over the plain walls with their little containers of non-toxic craft paints?
