That usually happens with too low of humidity and/or not turning. Maybe verify your turner, assuming you have one, is working properly.Yes definitely, so many things affect it. Now my biggest challenge is overcoming these guys growing stuck to the side of the shell..instead of with an air pocket on the end. I let them rest 24 hours after they arrived but it still happens this time. Going to search the forums and see if anyone has any tips or tricks
Some say for shipped eggs to store them probably like you did for 12-24 hours, put in the incubator, and not turn for a day or two. I've put them in and started the turner right away, and also did the waiting a day. Didn't matter one way or the other to me.
Humidity should be 40-50% and temp 99.5F. At lockdown (Day 18) the humidity should be around 70%. When they hatch, they'll drive that to around 80% temporarily.
I candle at 7 days to ditch the unfertilized/non-starters, and then not until lockdown when I ditch any that didn't make it that far. Some candle in the middle too. Again, I just don't like opening the incubator if I don't absolutely have to. Some are constantly opening there's to hand-turn their eggs a few times per day. I just know overall, the less I open mine, the better they seem to do.
If you haven't gotten a hygrometer/thermometer yet to verify, your incubator temp could be high, and your humidity could be low. I have four incubators, and only one is correct.
You'll get it down, and then it'll seem like clockwork. After hatching hundreds of eggs, I can tell you the anxiety doesn't lessen. I'm always excited when I've got eggs in the incubator(s).
