Don't even bother candling Marans eggs though. You'd need a super flashlight for that!
With broodies I'll candle once around day 15. I candle weekly when incubating in the incubator.
I do not candle at all.. I pick up the egg and smell it. I try to leave it all up to the hen. I have found ducks need more egg attention than chickens. My chickens always kick out the dead and weak.
