I am not going to get into the long-winded version of this, but here you go:

I had a major kinking issue with Super Cinnamons last season. I incubated 89/90.F and had no fluctuations that I am aware of. I posted regarding this issue and had some response from larger breeders making the single suggestion that I incubate lower at around 87/88.F as that is the temp their females find in the bin when coiled with eggs. The breeder that specifically mentioned 88.F being his females preferred temp when coild on eggs also hatched plenty of super cinnamons with no defects at all. This would lead me to believe that lower temps are preferable than higher temps even if we are only talking 2.F difference.

I may attempt another pairing that could yeild super cinnamons, and I will be incubating around 87/88.F this time.
