Forget what the manufacturer said. Take a good, honest look at your coop and picture 15 chickens living in that space. Do you think they'd be happy? Do you think they'd have enough space to move around? Do you think you could manage the manure of that many birds in that space? Would you have space to put a feeder and waterer? The answer to all those is NO.
You simply don't have enough space to add two more birds. Your coop and run both are at maximum capacity right now. If you really want these layers, you'll need to build more coop and run space. Or, your friend can find another home for her birds.
