The stallions have been turned out for just one month this year and this one has turned up at Longcross, within the haunt of Nelly and Blue. I'm not sure who he is and he may be one of the younger ones, out for longer but now displaced by one of the senior ones. The palomino pony is a gelding, trying, heroically, to protect the honour of his Mum and siblings.
Update: This is Oke Dene president - a four year old by Skywalker. He was turned out at Sloden but has been up at Hale and Turf Hill as well. How people are supposed to guess which stallion sired their foals when there are two or three possibilities without the use of DNA I don't know!
