I'm on day 23 with incubating chicken eggs, i had 3 left in the incubator that were showing no signs of hatching, no rocking, no peeping, no external pip today so i candled them and 2 were for sure dead, one was showing a lump inside the air cell and i could see movement but no beak like you'd usually see when they're internally pipped, the air cell is wonky and saddled shaped. Is that normal? Should i intervene? Or just leave it be? Really hoping it will hatch! Out of 4 eggs that made it all the way to lockdown, only 1 has hatched and it hatched right on time. My temp is 100 and my humidity is 73%.
