Come to think of it..I do the candling 1st to test my prediction before I crack the egg. Gets better with practice.
Here's a trick I use that I learned from someone else and have had very high fertility rate among the eggs I chose that will go into incubator. I might have a dud here and there...
I was looking on my cell phone before, now on bigger screen, it’s possible it could be fertile and the attached pic from cell phone is not very clear Either : (
I do see a faint ring on a pic.
