I candled my eggs just now....it's day 7 and I don't see anything.... on egg may have had a dark shadow under the air cell but I didn't really see anything else in the other 4. I guess I will try again on day 10 and if I still don't see anything I figure either the eggs weren't fertile or they got too cold before being collected (I got them from a guy in my town who usually supplies the classrooms with their eggs). Oh well.
