I have 7 eggs in the incubator, one of which did not make it. I'm assuming there was a hairline crack I missed and perhaps a small amount of yolk stuck to the egg tray..? I don't see any leakage but it is nestled very snug on the tray and the tray is not removable without removing the others eggs, which are at 2 weeks. I tried a drop of dawn to see if it would loosen it- did not work. Any other suggestions?
