I am always terrified of candling. I don't want to know how many duds, and I do not want to drop them. One time I carried the incubator to a bathroom to candle and I tripped and the eggs fell all over the floor. Carpeting--but the two that broke were GROSS and I had a terrible hatch I assume from them all getting jolted so hard. Therefore I am a non-candler type lol!
Oh I would have had a panic attack but sounds like an awful experience! I too carry my entire incubator to the bathroom to candle so I can see that ...slow motion...AAAHHH!
