I acquired these eggs from a friend who has a few pairs of Canadian Geese and is licensed to sell them... He gave them to me for free along with some paperwork. He said that Canadian Geese make good pets, I decided to take them instead of buying chicken eggs

! What day are they on? It would be much easier to tell if you make the room totally dark. You're looking for veins developing inside the shell.

You should have them on lockdown then. Have you boosted humidity? With the egg being all dark inside it does look like they developed.
