Hey peeps.... In order to see if an egg is fertile (viable for incubation), will I be able to see the donut after the 52 hour period like in the incubation sticky? OR - will the egg need to be in an INCUBATOR for 52 hours before viewing any donut? "52 hrs If you look closely, you can see the start of the blood island in the middle of the egg." If I'm totally off and I'll need an incubator in order to "grow the donut".... then is there any way to tell if an egg is fertile before putting it in an incubator? Sorry for the newbie questions. I'm used to hatching gecko eggs - where the ring is visible after a day without any sort of heating. Thanks!
