I've been saving a wooden plywood packing crate all winter, knowing the 23 hens will need about 4 nesting boxes. DH, because he likes doing such things, remodeled the inside putting in dividers to create 4 nesting boxes. I rolled it end over end to the coop and placed in the corner. Filled each with straw, placed the extra straw on the flat top for storage. THis was 3 days ago. THe first egg arrived today! Not in the next boxes but in the extra straw on top!!!
