This is my third attempt to hatch turkey eggs. The first two times I was using an old incubator and unbeknownst to me, it spiked during incubation killing the embryos both times. This time, with a 100% hatch of Icelandic and Marans under my belt I am using my Brinsea Advance 28. It's less than 3 months old. Yesterday was day 5/6 and everything was going fine until the fan and motor started making weird noises and then stopped. The over heat alarm went off and the machine kept stopping running. I tried to "spot check" the incubator and my super accurate thermometer only indicated "too low! to read." So i took the eggs out and put them in my old "spikey" incubator. They were at approximately 35*c / 95F for about 12-16hrs. Today I used a different thermometer in the Brinsea after resetting it and it said it was holding 37.7 so i have now put the turkey eggs back in. I'm wondering if my spotchek has an issue or if it's a incubator issue now... I can't tell you how badly I want turkey poults. Will 12 hrs at 35/95F have killed them or just "slowed" them? Anyone know?
