I still find it odd that if it were only related to your heat being a few degrees higher it would cause the same defect in so many babies. with thousands of other breeders out there using slightly different temps or just faulty incubators it seems it would be a commonly documented result of temps being too high at this point. I guess you'll never know for sure but adjusting the temp for your next clutches can be a starting point to rule that out.
