What a happy little colt he is! Where's the need to be afraid of anything if he's having such a safe and wonderful childhood, loved from the first moments of his arrival? :)
At the breeding barn I used to work there was a filly just like Zephyr. Bold, brave, extremely intelligent, active and cuirous - she started separating herself from her mother at the glorious age of 3 months, just going on exploring trips around the huge pasture along with other horses and looking for her mother only when she was hungry!
I have come a long way, to surrender my shadow to the shadow of my horse.
