so this is my first time hatching with an incubator have always used broodys before. so I've bought a brinsea mini advance fully digital,automatic turning. candled eggs day 4 all seemed ok developing nicely. I candled again today day 7 and embryos still developing but seem to be stuck to shell and don't rotate when I turn egg, I can clearly see air cell , then embryo in one half and other half is empty. will the embryos die? what will happen?
