Incubate dry until turning stops on Day 16, then top up the water pots and lock down the incubator and leave them to hatch on day 17 or 18 without disturbance. The shells are not so hard and unyielding as chicken or duck eggs and don't usually pose any problems, mine all hatched comparatively fast. The chicks are really tiny but grow incredibly fast, as you'd expect from birds that are laying eggs when 8 weeks old! Take extra care that they can't fall in the water pots because they are so small. Katie Thear's book 'Keeping Quail' is very useful, see Amazon http://amzn.to/J0CoVO
