Small air cell 21 days

[Newsab]

Hi im on day 21 with duck eggs and the air seems real small to me ?? What can i do

Duck eggs typically take about 28 days to hatch, so I would not give up, yet. This looks like a pretty good egg, to me. Just double-check your humidity and temp settings, and hold on. If you are turning them, you can stop around the 25th day.

Thank you so much for your reply .. there is lots of movement in both eggs.. i have temp at 37 an humidity at 55% is this right

I usually raise the humidity to 75-80% for the last few days. This Metzer article talks about that:

Lots of movement is a good sign!
