Candled 25 Malines eggs on day 7. 3 with blood rings, 6 infertile & 16 jumping embryos!
Had trouble stabilizing the LG after that. Found temp at 102.2 the next morning & checked an egg for signs of life. Still good! I'll let things be unless things start to smell funky in there.

have about 6 left but a few of those are questionable. We will see how many I get this week have about 20 eggs that are at day 21 tomorrow. The following weeks eggs are looking promising though I will be doing a serious candeling on them on sunday when they will be at day 7.
All my research & last year's experience, has led me to believe that 102 is maximum temp & I personally don't like it there for extended periods. Ideally, from what I've read, the temps should be in the 100-101 range. The circulated air units run best with slightly lower temps. 99.5-100. I increased humidity from 45% - 52% & I've noticed better stabilization of temps within 99.8-101.5 range.

Good luck SilverDuck!
