OK, all the info I've read says to candle the eggs after 7 days to see which ones are growing. I've never done this before, so I have no idea what to look for! Any help in explaining what a fertilized, growing embryo looks like (or what I should look for) after 7 days in the incubator would be helpful. Also, how much time should be spent doing this? It seems like opening up the incubator and candling 14 eggs would take at least 10 mins. I'm not going to screw things up, am I?
