Yes, we had a windswept filly 5 years ago ... if you did much research, you probably found out that this condition usually corrects itself beautifully, with no problems afterward.
From the pics, this filly is not too badly windswept. One can see it best from perfectly square behind the horse. It looks to me (first pic from the rear) like both hind legs curve to the right at the hocks ... a bowlegged foal curves outwards on both legs, cowhocked curves inward on both legs (at the hock only), but in windswept both hind legs curve the SAME direction, both to the right or both to the left. Difference is that windswept is NOT permanent.
When our 1/2 Trakehner 1/2 Arab filly was born she was worse. Thankfully, I had recently seen posts, etc. on other forums about the windswept condition and recognized it ... my daughter hadn't and was absolutely petrified because this filly was bred for upper level Eventing, one of the few times we bred to an outside stallion. The vet wasn't alarmed at all and confirmed that she should be fine with time. The condition is aparently not uncommon in Warmbloods and even Thoroughbreds. It's not often seen in smaller breeds, but does occur with large foals. Depending on the severity and the individual, correction can take as long as a year.
As I said, our filly was much worse and VERY wobbly when she walked, unable to trot. By 2 months of age it was barely noticeable and she moved well at all gaits. By 4 months she was COMPLETELY straight. I know you can't see much in this pic, but she is 4 months here and all straightened out

She herself has now produced 2 colts, the second by a large warmblood stallion, and both strong and straight. You really can't see from this angle, but here she is at age 4 years with her first foal

Again, windswept usually corrects itself as the foal gains muscle/tendon strength. All we did for our filly was give her sufficient exercise which, in her WORSE case (sorry I don't have any pics to show you how bad she really was) meant at first in a small paddock, then pasture. And, yes, she did grow up to jump ... cleared a 5' fence easily as a yearling ..... out of the pasture, then jumped back in again

when we went to catch her, lol. Now undersaddle, she schools well over fences and in dressage. She'll go into real work when this year's colt is weaned and she returns from the party leasing her.
