Free-range abilities of French guineas????

[keatonskeets]

I was wondering if there were any free-range differences between pearl-gray and French guineas? I've heard about weight, growth, and infertility differences, but does that make them slower at running? flying? escaping predators? cars? I've had pearl guineas for a year now, and they seem to wonder just about.... EVERYWHERE. Which in my case is a good thing. How would some French guineas differ?

I have both together along with a few lavender and they free range all over the place together.
I have seen them go almost a mile from the coop so far. They keep up with each other no problem.
