Hybrid BP

[CALM Pythons]

What are the concerns over hybrids? Scaleless corns, for instance, are a very accepted hybrid that is now obtained through scaleless x scaleless or het scaleless pairings.
Are these other hybrids, and the theee way hybrids, defective? Or too random with their temperament, adult size... like some hybrid dog breeds? Because those snakes in the videos are beautiful.
I'm not being a jerk, I really want to know what's up with this.
Thanks

How can we understand the needs of some of these dramatic Hybrids as the Husbandry needs could be anything in the cross.... Makes for a very tricky care sheet if not impossible to figure out when somthing is wrong/illness ect...
