I know many of you use 2x4's for roosts, so they are 2" wide I assume. Just wondering if they have to be that wide or will a smaller "diameter" work? I'm trying to make use of some scraps which are about 1" wide. It never gets very cold in Arkansas so frostbitten toes isn't a concern of mine, but I do want my ladies to be comfortable. My old neighbors free ranged and most of their birds roosted in trees, and my grandma's old hens had a board I think, kindof a ledge, so I'm really not too sure what they really need or like.
