Two of our 3 duck eggs that are due this Wednesday have started to hatch. Only one has broken through the shell. His bill is sticking out and he is chirping. He seems to be upside down. Is this normal? The middle one has a tiny,tiny crack in the middle, barely visible. You can see the air sack through the egg. Can someone please tell me how to download pictures so someone can tell me if these two look ok? They are in a classroom and will be alone until the am.
