I notice as I look at all the pics through out the threads that adult sulcata have many different colors. I notice a lot of the adults are a sandy color. (Not the ivory ones)And then I noticed some that we're darker. Their skin was darker and the dark outlines on their shell was still there. Is there a method of predicting these adult colors/patterns when selecting a hatchling? I notice (when there are multiple ones in pic together) that some are really light and some are really dark. I also notice that some have real thin dark outlines and others will have real thick ones. Can you predict from this or is it all random, as they grow it changes?
