![]() You must be keeping track of that, you had pretty clear ranges listed. Measuring incubation conditions actively, with multiple instruments, is the only way to have much certainty about what temp range your shelf is running at. Sometimes the “on a shelf” method doesn’t work in your favor, such as during some of the unprecedented heat waves we’ve had here in the west. Their siblings hatched in perfect health. Those eggs were all from a single clutch exposed to temps near 88-90º. Keep in mind that I’ve produced somewhere near 100 visual lavender corn snakes, I’ve seen 2 of them with a kink in the tail, and another that was, sadly, totally deformed. She’s also a new breeder, was a little overweight when I got her, and virgin clutches aren’t always the best. I really appreciate the effort and information, and I will keep it in mind if these het lavender neonates are not viable, but this specific clutch just never looked great. I recently hatched a clutch of corns at a somewhat varied temp of 83º to 84º, they are flawless and all eating frozen thawed pinks right out of the gate. I have never had a problem with kinking at 82º. The condition and size of the eggs when they are laid is by far the best indicator of vigorous offspring in my experience. In the 2006 season I hatched almost 350 colubrids, the vast majority were corn snakes, and all were incubated between 82-84. These days 82º F is my go to, and I’ve hatched a lot of different healthy colubrids at that temperature, including hundreds and hundreds of corn snakes. I’m not real comfortable with 85º for incubating corn snakes, but I have hatched a whole lot of healthy corn snakes at 84º Fahrenheit. The specific stage of development is also a factor, early-term heat spikes seem to be more dangerous than later-term heat spikes. Those dangerous temps in my experience (Disclaimer/specificity: This is for most of the North American colubrids in the lampropeltini tribe, of which corns are a part) run closer to 86º F or above for long periods of time, 12 hours or more but especially for days at a time. High temperatures do increase the occurrence of kinks. ![]() I’ve incubated eggs at a lot of different temps and using a lot of different methods, and I’ve had them come out with and without kinks in widely varying circumstances. Thank you so much for taking the time to reply, I appreciate you, and your friend, but I am unconvinced that this has anything to do with the Lavender gene, specifically. ![]()
