So I tried incubating a fertile egg from Trader Joe's having read about other people who tried it. Well having compared it to photos of fertile eggs from day 1-3, mine definitely was a dud. I carefully opened it up and no sign of life whatsoever. I think the eggs being 2 weeks old was part of the reason. I'm tempted to try again with another egg from the same carton but I'm afraid of getting the same results. So...my question is should I try again this time or wait?
