No, inside the coop there should be horizontal tree branches or 2x2 lumber around 18" from the ceiling and at least 12" from the floor for the hens to sleep on

ETA Also I don't think you grasp the problem with 17 hens in that little box. It is a welfare issue, it is not a question of how many chickens you can cram in there. If hens are that closely boxed together you will get feather picking and bullying and this will eventually result in cannibalism. It will be a breading ground for disease and parasites and one of the above comments is right, even with a lot of bedding in there an 8square foot house with 17 hens in it will need daily if not twice daily cleanings. Personally I would not even consider putting more that 4-6 hens in there and most keepers would only put 2 or 3
