well the first temp spike was with the first eggs and didn't drop the humidity much- none of those 4 hatched. (due to too low of humidity it was only 25% 1-18; Raised to 45% in Hatcher)
the second one happened with the last hatching, it dropped the humidity to zero on (Feb 3 late) Hatch day, 4 had hatched early (Feb 1 & 2nd),
and the other 4, 2 had internal pips, 1 never piped at all and 1 was infertile or an early quiter (no blood veining when opened).
this time I am not changing them from the 1st incubator (at the moment we have 5 of the 7 eggs still moving). as stated above.
I will just remove the turner, candle and return the eggs to the incubator in a Carton, then raise the humidity for lockdown, then we will see if I can hatch better with the Fan.
ETA: I will not add anymore eggs until this batch is hatched. I was adding eggs with the first hatches, so they were staggered hatches is why I used the 2nd incubator as a Hatcher, plus it didn't have the turner or the fan. I thought it would work better to just rotate the eggs to it as I candled, I already had the humidity and temp stable for lockdown. (I thought)
sometimes my own thinking gets me in trouble.
