The lady who has the other pony at mine, her little boy is about 4 or , and has was happily munching away on a hoof pick last night. Until we realised and said "errrrr..... dont do that, you're kind of eating horse poo!!"
Then last night he was sick etc all night, she blamed the hoofpick, and thats what he got told.... dont think it was that, but then dont think he'll do that again.
