I candle pointed end down BUT my eggs are still in the turner. If you have a good candling light you should be able to see veining action and webbing wending up to the air sac. The ones that are questionable come out for further inspection. (And then if I'm still unsure, they are placed in a separate row in the turner so I can check on them later to confirm a stay or nay.)
Some egg colors are easier to candle than others, but sufficiently along (Day 7 to 10) you can tell the difference between webbing and clearness (Day 10 for Marans as their shells are really dark.) I candle at Day 7 or 10 initially and then one more time before the final candling at lockdown.
