I have four hens, and am about to add nesting boxes to the coop, still a little early I think but might as well get them done and installed now. My question is I know with four birds I could get away with one box, but plan on putting two in. Can anyone give me some standard dimensions for a nest box? I really have no idea how big to make them, also do you just use the wood shavins in them, or should I use some sort of other bedding material? Thank you for any advice you can give this noob. Have a wondeful day.
