Hello this is my second batch of eggs for quails I'm trying to hatch. What's the earliest you can see anything inside the egg with a torch? It's day 3 and Alls I can see is orange and some shine blue and some shine clear white inside. Shouldn't there be vains by now or something? I remember last time seeing vains not so early though and the embryo

By day 3 you can see development but with coturnix eggs it's hard. When I candle, which I don't do often, I wait till day 7. At that point the eggs will light up green if they're empty or only the air pocket will light up and the egg will be dark if there is a chick. With bobwhites or chickens you can see the veins develop but the dye on coturnix eggs makes that difficult. You'll get better hatches if you don't handle the eggs though. I don't candle unless I don't have enough space in the hatcher trays.
