I couldn't get a decent picture from the video I had my daughter take but it seemed to have 2 black eye spots at either end (pointed and round) I originally thought it was just a huge yolk when I candled it when I first put the eggs in.
In all honesty I would rather it was just 1 because at least there is a higher chance of survival.
When I ordered eggs online I had no success I believe it was partly the eggs and the awful incubator I was using. However this time I got the eggs from my call duck (who only started laying on my bday, 20/02/22

) I also have a much better set up thermometer, incubator with automatic Turner ect...
I also have a bit more knowledge and lovely people here to help me with my issues.
I guess only time will tell but the egg is bigger than her usual ones and weighs more than the other eggs I put in at the same time.... its just a shame I couldn't get the video on here but cest la vie
