I can't seem to see your pic anymore, but they looked pretty good. Do you have measurements and weight on the cornutum juv? I would like to compare to his sibling and see how they match up.
I have two three year old females that are siblings, and one is twice the size/weight of the other. The small one was a runt right from the start and has always been a very lazy eater. I don't think she would have survived in the wild at all.
She was in someone else's care for a couple of years and just came back to me last month. She's not looking very well due to a late hibernation and some neglect when she did come up. 
Anyways, There aren't many CB cornutum around and I think it would be a good idea to make the most of the data if we can. I'm happy to share the info from my side as well.
