What are you using for a flashlight? Fresh batteries? Are you in a COMPLETELY dark room? No windows, no LED's from electronic equipment? Did you give your eyes time to adjust? Are you blocking all of the light from the flash light, so that no light shines out AROUND the egg? What color are your eggs? Very dark eggs, especially the blues and greens are very difficult to see into. Do you have water in your bator? You might want to drop the humidity down to around 30 - 40% until lock down. Check the air cell size chart in Hatching 101 in the learning center for comparison.
