When I first started with my new OTTB a few weeks ago, I noticed he was doing something weird while he was standing at the tie rail. He took one of his front legs (believe it was the left) completely across the other front leg and stood there. I made him stop and he did this twice a few weeks ago. I had not seen it since, but today I had him tacked up and was hand walking him to the arena. I was fixing his girth (while he was standing still) and he did it again (same leg). This time I had to pull the left leg off the right one and had him stand normal again. After that, I was standing to his left side with my back facing his left shoulder, as I was fixing his reins or something. I didn't see what happened, but his left leg then struck my hand and left hip/side.
He only 3 yrs (off the track almost a month), but is NOT disrespectful at all, so him striking took me by surprise. His gaits appear fine and we even started working over a trot pole yesterday (though he has walked over a series of poles and over raised poles.... and was also lunged over fences prior to me getting him). When he crosses his legs, it is not just crossing them as in standing with both feet on the floor... he completely wraps his lower left leg across the front of his lower right leg (meaning he is only standing on three legs). He is sound and there are no visible leg issues (swelling, etc.). If not for the crossing, I would have no concerns about his legs.
Any ideas on what this could be caused by or anybody have any similar experiences?
