I mentioned in the picture forum that my colt is going through this stage of not wanting to be caught...well, the reason is that he can see the mares (several of which are in heat now, of course) from his paddock. Smart little bugger that he is, he knows that being caught by the humans means leaving his lady friends. So he's having none of it!
I've never worked with a stud this young, and this is the first time I've experienced this kind of behavior. I think in John Lyons' first book, he talks about the difference between the sexes; that the real difference when it comes to stallions is that mares ALWAYS take first priority. Its interesting how such a simple thing drastically changes how you approach training problems.
In this case, I had to fall back on a strategy I've NEVER had to use to catch a mare or a gelding; free lunging in the paddock, making him move his feet until he made the decision to come to me. Waiting him out didn't work. Food didn't work. Every trick I know about body language and approaching horses in the pasture...no dice :P And all this from a horse that usually trots right up to you when you come through the gate! So I found the whole experience rather eye-opening...its one thing to know something intellectually, and quite another to deal with it first hand.
