We were supposed to have 4 eggs hatch this week but all 4 were dented and starting to soften and even mold a little. Knowing that they should be close to fully developed we opened one and found an underdeveloped embryo not even close to hatching. Any ideas on what could have caused all 4 of these to go bad?? Just a stroke of bad luck?? They were all incubated at 82 degrees for 23 days then moved to 88 degrees, the incubators are monitored digitally and don't exceed a 1.2 degree variance from the 88 degrees. We have already hatched 10 leos and 8 AFT's this season using the same methods however I am concerned because there are some eggs due to hatch next week and I see a couple dents froming again. Thanks in advance!!
