I have tried three batches of eggs this year already and all have died. #1: 11 eggs - 8 died - day five - ish - 3 lived until day 18 #2: 22 eggs (from bycers) - all died 10 ish #3: 17 eggs - 12 made it to day 16 The first batch I was trying to do w/o a turner and crazy hours for school, with a broken thermometer. The second everything was brand new - some of the eggs had moving airsacs (never had this before) - completely my fault The third I had a thermometer that was SEVEN degrees off - I adjusted my temperature and I think that is what killed most of them. Interstingly enough I also found mold just on the inside of the airsac of one egg ( it had recently died) I just started my fourth batch of eggs yesterday night. Also, from a BYCer - Countrybum. I won them in a contest that she held about a week ago. All arrived in perfect condition. I put three of mine in with hers. All are numbered/ the temp is perfect/ the humidity is sitting around 60. All is well....... I will update and add pictures through out the process... Wish me luck I am going to need it.
