I just got my 14 hatching eggs from ebay yesterday. I candled them all to check for breaks, and didn't see any. I rested them in my prepared incubator for 12 hours, and then turned the roller on.
I plan to wait until day 12 to candle them all again.
Just went into lockdown. I am not that optimistic anymore, but we shall see what comes up, will update in 5 days. Looking like probably only 2 on the way. But I am still new to this, and the eggs I received were a bit speckled when candled made it hard to see.
