At 10 days, I'd expect to see the dark area filling half the egg. It looks like they have stopped developing. Give them a few more days (day 14) & candle again. If there is no more development then something has happened.
Did you have temp problems? Did you calibrate your thermometer? (maybe your incubator temperature is low?)
Yes, I have had some temperature issues... I'll check them again in a few days and see if the dark area has grown. Is it possible to slow development without it stopping completely?
