I'm hoping to get some nest boxes together this weekend (my flock currently is completely free range and sleeps in the trees, but I want to (a) have a predictable place to find the eggs and (b) get them used to the barn as winter approaches). Just some basic dimension questions: how big should they be horizontally, how high should the sides be, how high off the ground should I put them (they'll be bolted to the wall of the barn stall), and how far apart should they be? I've also noticed that they like to lay under bamboo branches (I have huge groves here, and always have piles of the stuff laying around as I'm harvesting and thinning it). Should I suspend a bamboo "roof" over the nests? Also, should the "floor" of the boxes be solid? I'm going to build the 1.0 versions out of old pallet wood, but I was thinking of making nicer ones out of bamboo during winter when I have more time.
