Duck eggs with small air sac

[homestead 101]

It day 22 and I am really worried I might have made a big mistake. The air sacs arm to be a lot smaller then ones I find online.

Is it to small or am I just worrying to much. How would I increase it.

Sponge the eggs with a wet sponge or washcloth at least once a day until air cells look big enough...

I know, it sounds counterproductive, but the process of the water evaporating off the shell actually sucks more moisture out of the egg... humidity will spike at first, but after it evaporates it will come right back now, no prob...

When you spray them are they sitting in the bator? Are you drying up the water pool under the tray after spraying?

I have a brinsea mini eco. So no I do not wipe up the extra water. I guess that would creat to much humidity. I will sponge them from now on

Or set them on a towel on the counter, spray and replace in bator... I only thought of that because a friend of mine got Call eggs from me and had the same issue and the same bator... we talked back and forth for quite a bit before we figured it out, lol... once she fixed the pooled water issue, the air cells got back on track quickly...
