I have a wacky feeding schedule and rather like it, my horses never know if I'm coming outside to catch em or feed em, lol. I feed anywhere from in between 6-11am and about the same time frame at night as well.
The wind may be making her feel spunky and since she hasn't known you for very long, she may not be attached, so may be playing some games. Geez, I've had so many horses make me walk around the whole pasture trying to catch them!
Another thing you could try is the pen all the horses up in a smaller pen in the pasture at feeding time, so they are used to going in one area, then snatch her up from in there!
