Muddi-
By the way, I got frustrated with my still air hovabator after that first hatch and bought a small fan to upgrade it to a thermal air incubator...NIGHT AND DAY DIFFERENCE! I have much fewer temperature fluctuations, and fewer early embryo deaths. I have yet to see how my hatch will go but so far it's been so much better. I bought the thermal fan on e-bay for 99 cents plus shipping and I am so glad I did. I would highly recommend upgrading your 'bator for the next hatch. (with thermal air you incubate at 99.5 degrees).
Hope that helps!
