Air sack

[bscarlata06]

Hello I am hatching two Pekin duck eggs and this egg has a significantly larger air sack. It is day 20 and I am worried this is too big. Someone with hatching experience please let me know!! There is movement and veins in both eggs.

When I hatched chicken eggs, the egg that had a larger air sack ended up not making it. It looked completely healthy other than the air sack. It hatched, but the baby ended up dying. It was too weak. That may be the case with your egg, but I'm speaking from chicken egg experience, not duck.

Can you show a picture of the other duck egg
