The air cells look good I find that my duck egg air cells don't draw down till after lockdown
That is weird but if it has pipped then it is a weight and see moment
Also I would candle the eggs every time I roll them just to be sure their are no internal pips
Good luck with your duck/chicks
Hi
Super exciting that you are going to hatch ducklings (I have 1 call duck egg in the incubator right now she is on day 9 we are picking up some more eggs today, why do they take so long to hatch :he:lau)
Some breeds take longer or shorter to hatch bantam duck breeds like the Call duck take 26...
