@Luv Ducks here is your picture of your little darlings 😍

We paid up for the Brinseas exactly with the idea that if something goes wrong, we'll know it was not the machine so there is one less variable we need to account for.

The process is:

- set humidity low like 40-44 % until day 24 or whenever chirping starts (in our first hatch we did 50-55% humidity, air sacs developed super weakly, 20% of ducklings survived, so we're leaning dry)
- temp to 37,5 C
- starting from week 3, until the day above, do the daily cooling for 20 min + misting with a plant sprayer (fine nozzle)
- in the final stage, stop turning, boost humidity to 70%+
- whenever we see an attempted external pip, check with candling where the safe area is (no veins) and enlarge it if OK

The biggest problem we seem to be facing is:

1 - some embryos starting but just not becoming fully formed (giving up in week 3 or so?)

2 - some ducklings, while fully formed, being seriously entangled, almost like tied like in a knot, upside down, etc, unable to find their way out in a good place, eventually dying even if we try opening the egg but are too late (because we waited as not to cause bleeding...)

Regarding 2, I see that as possibly weak genetics? I don't really see how this could be fixed by using a different hatching method.

We noticed that Khakis tend to pip very early (days 23-24...)
My 2¢: Something went wrong during the eggs journey through the postal system. Not all mail-services are treating egg packages as special as the USPS does. If eggs are exposed to harsh acceleration, especially of the twisting kind, the embryonic disk can be damaged.

Ha I should send you the picture of my welshie egg box. It was covered in fragile stickers which meant punch a hole in the box and drag it behind the truck. I only got two of 18.

This was my explanation for the low result with the Welshies -- but this last batch, the KC's, were our own eggs which have hatched at 80% in the previous year, so now I'm just ... puzzled.
