I have been reading through the forum and now I have a question...our chicken coop has 3 shelf areas. They are separated into six areas by a piece of wood in the middle, but it is not a "box" per se, where they would actually be sitting "in" it. It is a shelf. Do they need to be sitting down IN something in order for them to nest and lay eggs? The areas are covered in shavings -- should it be deeper, like with hay? We have had them for a week and we are not sure if they should be laying yet, or when they will start (they are about 3-4 months old). I am hoping it is not because of the box thing. Any ideas?
