Got a new BCI today

I'm glad to hear it isn't unheard of, even if it isn't really common! Did you notice if the babies that react like that tend to use hides more than others?

No, but I didn't really look for this (I didn't notice who used their hides more than others in litters that were born here). I used a rack system for babies so not super easy to see if or when they were in the hides.
Sometimes they'll sit in the corners because it feels more secure (more of the body touching surfaces) than actually being in the hide.

I didn't realize that albinos and sunglows often dull out some when they grow up so that's useful to know.

Yes, colors fade and all boas get yellow coloration as they age so albinos/sunglows (since missing the black) get very yellow as adults. Definetely good information to know
For example, here's an albino I produced a while ago, as a baby:

As a young adult:
