Had an interesting situation yesterday. Some big bales of straw had been delivered to the yard, leaving just a narrow pathway between bales for the horses to go through to get out to their field. The gap was narrow enough that the bigger horses would rub against the bales on both sides as they went.
So, I took the horses out one by one, on very long lead ropes, to see what they would make of it. Benson, Flynn and Paddy viewed it with mild suspicion but walked through of their own accord. Tigger looked at it, snorted, investigated, backed off, and after about 5 minutes and some encouragement leapt through. All pretty normal so far. All of them coped, without getting overly anxious and put up with something a bit challenging to get to the field.
Elvis - approaches, stands still and looks at it. No snorting, no movement, just looking. After a minute or two, he aims at the single bale, approaches at a brisk walk, puts his shoulder into it and rolls it aside. Then walks calmly through the big gap he's opened up. Deeply impressed - one truly problem solving pony!
