The coloring on yours is very unique. I don't think it has any melanistic mutant in it.
It looks bigger than a Kansas blue back. Maybe a Chinese ring neck crossed with machurian
Windy weather makes them more skittish for sure. A pheasant will double back, zig zag etc. Anything you can imagine. I've trailed a dog over 200 yards trailing a rooster.
In snowy conditions they will run, yes. They also are more likely to borrow in and hold tight. Warm conditions more likely to run. I'm puzzled I am the only one who thinks this.
