The title pretty much says it all... I had a hen abandon her nest (I don't know why I seem to have all the hens that stink at being broodies!! ) so I candled the eggs and found two that were developing. They were cold when I found them, but I put them in the incubator and checked later, and saw movement (yay!). Is there any way to guess when to lock down when you don't know how long the eggs have already incubated?
