Find this abit strange.

I've had my 3 girls coming on over 2 years now

I originally had 2 and added a 3rd in to the mix with no problems.

But I find it strange my newer piggie is soo much braver than my other 2 girls who I've had longer.

She doesn't run away much at all
And enjoys a head rub sometimes.

But my other two have none of it. And always run away more often.

It seems they dont copy the behaviour of the brave one a vis veras.

I think that just like people all piggies have different personalities.
We have had some brave ones and some scared ones over the years, and whilst they do learn and copy from one another I also think some will always just be naturally more reserved or nervous than others.

So basically they are stubborn and set in their old ways lol

No, not stubborn. A lot is individual personality but a lot also depends on how relaxed or stressed out their mother was during her pregnancy and how confident/wary she was during the nursing period. Babies from highly stressed sows experience these high stress levels as the 'normal' default setting and the wariness of their mother can imprint deeply on the offspring with some variables for their overall personality.
A piggy with timid disposition will be naturally more affected than a sibling with a somewhat more outgoing disposition. But it can be very difficult to impossible to work past the settings that go back to before their birth.
