I need some help.I am having staggering hatches.The ducks would not sit on them so I got upset and nervous and brought them in and put them in the bator.well I can tell most all are fertile.Some more full than others.I see veins,and then I look down and then I see this little black dark spot.Is everything ok,it has movement.Most all have movement.I started putting them in last Monday,and have put more in every since.I stopped Sunday.What do u think .Have I done the wrong thing.I have hatched a lot of eggs but this is my 1st of doing like this.And I have not wrote down much of anything. Someone tell me if I am wrong or what to do,,,,,,,Thanks if you have any ideas.I don`t want them to die.   Sandra
