I also have my hens in a shed. I went to Home Depot/Lowes and got the stackable plastic shelves for not a lot of money. I set them up like stairs in the shed. In my case I have closest to the ground the legs not the shelf, so they can go underneath in inclement weather. Then the I have two one level sections, and one two level section, the second level being on top of one of the first, if that makes sense. I put two nest boxes in the section in between the first and second level. All shelves are covered in hay which I pick out daily with a latex disposable glove which keeps it smelling very nice.
I'm lucky in that I'm in NJ all the time and can pick up fresh bales of alfalfa mix hay (right now they are selling alfalfa/second cut grass hay) and am a regular customer of a Tractor Supply there. I find a bale of hay lasts about a month doing this. I have 8 adults, 3 pullets bedded on this.
