I'm all ears if you want to try some other experiments with future hatchlings I get.I've had a similar experience with my 4. One just seems to grow extremely smooth while the other three have had some minor bumps along the way. All are in the same conditions.
The variables I'd love to explore are genetics, pecking order as it relates to microclimates/behavior, and stress (corticosteroids - again tied to pecking order). I lack the necessary time, resources,funding, or sample sizes for this...
