My 2nd hatch hasn't gone nearly as well as the first. I have a Hovabator Genesis incubator and I set 23 eggs in my 2nd batch. On day 18, I was down to 18 eggs that had a "dark blob" on one end and a good air sac on the other. Several eggs pipped on day 20, hatched on day 21. In all I have 13 "babies" right now on day 23. I have one that completely zipped the shell and then appears to have died (??), no movement in 2 days. Another was zipping last nite and this morning is doing nothing. Temp is 99.9 to 100.2 and humidity is a constant 72%. I also have 3 eggs left that have done NOTHING. Should I let these stay in the 'bator a while longer or is it a hopeless cause? Any ideas what I did wrong this time? I thought I did everything the same as the last batch in which I hatched 13 of the 13 I placed in the 'bator on day 18. Maybe I am expecting too much?? Any suggestions are appreciated.
THANKS
