where are you looking? unless they are very young neonates right out of the egg or adults that are breeding, I can't recall ever seeing chondros (or any morelia for that matter) cohabitating.
you've been given some good advice, but ultimately it's up to you whether you intend to put it into practice. I'm not sure your best angle is to try to look for inconsistencies in the husbandry of other animals that don't pertain to your collection.
good luck and keep us posted.
