Hello, so this was my first time breeding, I paired my bumblebee to my pewter lesser, I was thrilled when she layed her clutch of 5 eggs (first time mom) the incubation went good, everything was perfect, i decided to cut on day 52 because the incubator was running on the warm side at around 90. They where all alive and looked good i checked on them every day sometimes twice after I cut. On day 56 I saw that all there heads where up except 1 so I looked closer and saw that the umbilical cord was wrapped around her so from doing research I decided to cut it, but unfortunately the the next morning she didnt make it. Now just this morning day 59 I checked on the remaining 4 and 3 of them had also died all there heads where out one was even have way out of the egg but looked like he got twisted in the cord and stopped the yolk from being absorbed, afte looking at the rest I noticed that they all had big yolk sacs and appears that they hadn’t absorb any except the only one thats still alive, I can see the yolk going in him throught the ambilicul cord I hope he makes it. I regret cutting that early and think that could be the reason they didn’t make it. Next season im defintly waiting till they start piping
