Arthur's bleeding nose Part I. He also tries to get close to Cleo and nuzzle her.

Arthur has some blood coming out of his nose, one nostril only. We're not sure what's caused it. It only happened while we were with him.
While cleo is not feeling well with colic, he tries to nuzzle her from behind. He ears pinned, she doesn't like it. She eventually settles down and accepts the comfort from the herd. This is a great stride, as it means Arthur is stronger and healthier. She wouldn't allow him near her when he arrived. He was so frail. A frail horse might mean a sick horse and the herd seek self preservation and keep the sick horse away from the herd.

A video on Cleo not feeling well https://youtu.be/s1G5YeeUBxc. She is doing well.
