@Enchanted: Ponies are both doing fine, little weight issues with both, but nothing major. Heta gained quite bit of weight(like girth used to go to holes 7/8, but now it's at 5 and sometimes I can get the other side to 6) during December and it's not coming off so fast it seems. : P Heta's leg hasn't been bugging her too much lately either, so I'm thinking the December holiday was timed pretty well.

Tý on other hand has been with the new little boys since fall so he can get some extra food, while the other boys of his age(and older ones) could use to loose bit weight so they don't really get anything extra. He's not really skinny(at least he wasn't in January), but certainly isn't fat either, so little extra is probably good to keep him growing nice.
XD Willy seems like his quite a character, now that he's getting more comfortable with people.
Sometimes blocks are not enough to get minerals. Or the block lacks some mineral... :\ Ground licking/eating is tricky and I don't think anyone has cracked the reason behind it(or it can vary). Like in collage there were some horses who were crazy about eating sand(crazy that even with 'buckets' on their nose, they still worked around it to eat sand)... While I think in their case lack of minerals was ruled out, but boredom was another possible reason seeing most of the worst were not really ridden. Though I don't think all stopped the sand eating habbit even after they were exercised more and some that were regularry ridden still ate sand. As said it's tricky. Though in Willow's case it really might just be boredom, if it started after Sky passed away.
@MochaTheLlama: Oh, wow. That lunging/ground work situation sounds really scary. o_o Tý was sort of like that just before I moved him. Still don't really know what triggered him then as after moving I've only heard good of his behavior. In Harley's case, I might have had him checked out for any pain reason, as it does sound to be quite sudden change in behavior and sudden major changes usually have a reason behind them.
At least you can hopefully still enjoy nice rides with Poco to cheer you up some. c: And good luck with horse hunting too.
@blazesong: Quick googling and I found gray standardbred stallion(goes by name Jet Laag and I think same horse also goes by Jet Laag USA).
http://www.empirestallions.com/empire-s ... /jet-laag/ While roan is possible in the breed, but it's pretty rare. Even rarer than gray I think. Didn't find out his birth color, but most likely bay. So the horse in question is likely just going gray and not roan.
