Most horses stand with their front legs scissored apart when they are eating off the ground. Raven alternates between legs, but Tonka always stands with his right leg back and his left leg forward, probably because the heels of his right hoof are quite high. When Tonka first arrived his scissor stance was very wide and he often had to shuffle his legs back and forth to get into it. Over the past two months his stance has been getting narrower, and in recent weeks I have actually seen him graze with his legs straight under him (I think of this as the equine equivalent of being about to touch your toes without bending your knees). I'm not sure what it means, but I think it's a good sign.
