I have to chime in to disagree with dr del here. I understand we do not have a sound statistical data set to prove that lower incubation temperatures can reduce kinking in visual Caramels, but at the same time, the lack of that data set precludes his claim that "it hasn't worked for any of them", and I do not agree that "it's all BS and greed". What I see is the generally shared view based on many dedicated hobbyist and breeder anecdotal reports that lower incubation temperatures appear to reduce the likelihood of kinking in visual Caramels. In our personal experience, we have incubated below 88 deg F and our Caramels came out great. Therefore, any time we have Caramel eggs going into the incubator, we make sure the temp is below 88 deg F. Even if we get a kinked one in the future, I will be inclined to believe that we could have had more if we were incubating higher.
