Oh and do NOT open the lid of the incubator if any are pipping as this can dry out the ones that have pipped and this causes them to stick to the inside of the egg and die. So if you need to add water or remove turners or add some sort of no skid surface, do this before external pipping. And if you absolutely MUST open the lid during pipping, what I do is have a spray bottle full of luke warm water and I open the lid as fast as possible, do what I need to do and spray the inside of the incubator, eggs with a good soaking and then quickly shut the lid. Usually this keeps them wet enough as to not dry out. But I try not to have to do this at all.
