Well I’m violating all rules about opening the incubator during hatching, and I have this long staggered hatch going too! Bacteria grow wonderfully in warm, humid conditions, and my incubator is full of eggs encrusted in rotten yolk. So I’m keeping the humidity at the lower edge of acceptable for hatching, just barely over 60% so as not to encourage more bacterial growth than necessary. That means that I have no wiggle room in humidity, so it drops to 45% when I open the bator.I only ask because I had both sticky chicks and shrink wrapped chicks in my last hatch. Sometimes additional things are at play. I read once sometimes stuck chicks can be a result of turning too.
There’s so much at play, it doesn’t always fall into a formula of X causes Y. Sometimes X causes B which causes C which may or may not cause Y.
I’m also with cluckndoodle, opening even quick can set some things in motion. I use warm spray water to spike humidity. Or I wait until a chick hatched and it’s wetness spikes humidity.
It can be a crap shoot. A five second open could dry out a chick. But I’ve pulled an egg out at least five times to check progress, it had to be out at least ten minutes total to work on it, and STILL had them hatch on their own. No shrink wrapping.
I know none of this helps. Just passing along experiences ...
I don’t want to leave the newly hatched keets crawling around all of this yuck, so I’m pulling them out as they hatch. Just got two more out this AM! Humidity plummets every time I open it, and I still have pipped eggs, so I’m just hoping for the best. I also have eggs I’m still hand turning in there - should have left those out with guinea moms until after this hatch, but I didn’t know if they’d take their eggs back...
