Robyn, The head down thing has always posed a question for me and you addressed it. Does he relax because he has his head down or is his head down because he has relaxed? Hunter is a horse whose normal head carriage id pretty high all of the time. He certainly does drop his head when he's relaxed but I'm not sure that lowering his head would necessarily cause him to relax.
He's also of the grab a mouthful of grass and chew it up fast before something bad happens type. Nancy
