candeling question

[veggiecanner]

do quail eggs ever show the green glow for any other reason that infertility?
what would a early quitter look like in comparison?

Are you talking about eggs before incubation or during?

 

[veggiecanner]

I've been candling on day 6-7 and removing the non fertle eggs. But some more show up on day 14 or 15.
I am wondering if the early quitters look green. If not what would I be looking for to tell the difference?
I was wondering if I was missing some Of the clear ones or if some thing is happening to cause some deaths.
