Nice hatch!
most were mine. i move them around alot during incubation. maybe they got too hot? idkI'm certainly not an expert, but I know you've had higher % hatches previously. Were the non-hatchers all on one shelf or interspersed throughout? (don't you have multiple shelves?) Only thing I can think of is double check everything, temp, humidity. Where did you get the eggs? From your flock or did you purchase them? Were they older eggs or pretty fresh?
I think you figured it out! Good luck on the next attempt!. i think the temp got too high so im going to back the set point down 1 degree. the last hatch was 3 days early
