Okay, I managed to snap some more pics of the hatchlings. It was a pain to do it one handed while they squirmed around, but I hope they are decent enough. Here are top, lateral and ventral shots of every one of them, in the same order I used on my original post:

And I also managed to get a couple current pics of that cinnamon looking pinstripe from last year. He actually ended up with a friend of mine, so I just asked if he could take some for me. He looks even more like a cinnamon to me now that he's a bit older, but the dorsal stripe still looks a bit too bright, especially going back towards the tail.

Anyways, I'm really grateful for all the insight you have been giving me. It has been super helpful. And even if we don't manage to pin down exactly what's going on with these little guys, it's always fun to discuss genetics with other ball python enthusiasts!
