Confused about eggs

[aldren90]

If my eggs are 10 days old and are geese and duck eggs and have a air sack are they gonna hatch but I can still see the yolk and nothing else

You might not be able to see good enough to tell if they are growing good or not.
I would give them more time till you can tell by the eggs being dark from the chicks.
Good luck!

A unfertile egg won't have a air sac. It will just look like a egg with a yolk in it floating around. If it is fertile it will get dark and the big end will have a air sac

When you say your eggs are 10 days old, do you mean they have been in the bator for 10 days? If so, you should be seeing veins developing. Please don't be mad, I have to ask, you do have a Gander and drake for fertilization? If so, they could just be young and not fertile yet. I hope this helps. Good luck.

Quote:
That's not true, the air sac has nothing to do with a developing embryo. It 'forms' from evaporation of the contents of the eggs.

Most duck and goose eggs are white, if by day 10 you can't see any veins, chances are you aren't going to.

All I can see is that there is a yolk in side and when I move the egg on the light it follows and it isn't that dark and yes they have been in the gator for 10 days since they came out of the mommas behind the eggs have bulls eyes and I watched my geese and ducks mate so their fertile and all are over 1 year old and I CANNOT SEE ANY VEINS.
