Your hygrometers are way off. I stopped using the digital ones. One they are never right and two they are never right. I just add water to the middle well in plastic tray and don't add any more until lock down. Is there any way you can get fresh eggs and not shipped, so you can practice? If not you will end up spending a lot of money and thinking you stink at hatching. When I first started hatching I bought eggs also. Had bad hatches and swore I would never do it again, then I collected 25 of my eggs, saying I will be lucky if only one hatches, they all did. It takes a few tries before getting it right. Good luck, Michele
