I have some marans eggs in the incubator..they are very hard to candle..Im afraid I may already know the answer but here goes..In all but two of the eggs I can make out a "doughnut" like ring that circles the whole egg and its pretty thick..Im afraid those eggs were scrambled in transit..the other two I can just make out a small dark mass floating near the top..Thats all I can tell..Tell me what you think...Thanks
