I have two questions. One is will cypress shaving be ok to use in a small run? Like under the coop. I like cypress because it's heavier and won't fly around like pine. And my second question is can a window at any point be considered to large? I have a neighbor with about 30 panes of tinted glass that are around 32"X 36". He says he'll never use them so I can have all I want. I was going to try one in the chicken coop and about 4 in my wife's potting shed. The one I'm going to build after the coop is done. These panes actually came from the Atlanta airport from some demolition work. This is tempered glass with some tint. Good or bad?
