Glad you have time and patience to devote to this integration because it's going to require an abundance of both.
I would give the flock and PG the space to work things out on their own and just keeping an eye out for a couple of issues.
The first one is if PG is losing weight from being bullied away from the feeder. The other would be any signs of bullying to the point of injury. With a small flock and lots of space, neither issue should become a major problem. Continue to make sure PG gets extra to eat and spend time observing flock interactions. That will let you know if you need to intervene.
