It must be the strain that determines how handleable and tame they are. Everyone I've spoken to, both in person and online, has the same problems with the natal rats here in the US. They don't like being handled and bite a lot. Some seem more aggressive than others, but none like being handled like you show in your pictures.
With my first 2 litters I attemped to handle them a lot, a couple times a day from birth. By the time their eyes opened they no longer allowed this, they would jump away every time and refuse to be handled.
With the current CDC (Center for Disease Control) and FDA (Food and Drug Administration) ban on imports of African rodents do to the MonkeyPox scare, we are stuck with the strains we have here in the US so I don't see it getting any better. Plus since they are almost exclusively bred for feeders, the strains that are here have been extensively bred for generations with minimal to no handling.
