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.
Good luck and don't give up! Are you incubating them vertically? Sometimes when they're done vertical it's hard to see the veins at first because they start right under the air cell.
