Duck egg air sack

[Nikki211]

details:
Incubator temperature between 38-38.2°C
gets misted 2-3 times a day / turned
Waiting on a thermometer to check the humidity
Imagine below attached to get the appropriate information needed

The duck is is on day 19 and I’m worried the air sack is a bit bigger than it should be but everything looks fine there’s movement inside . Only reason I’ve joined is to get the right information as there’s not much on the internet even if I sit there for hours to find the right images or information . So what I’m asking is should I be worried about the air sack ? Is it normal ?

I think it’s fine. Waterfowl eggs are different in that they need more humidity than chicken eggs. With duck eggs you want to open the bator once a day for atleast 15 minutes let it cool and spray the eggs then just put the bator top back on.

Okey thank you I’ll keep small updates on it as I don’t want to do something wrong
