I seem to have accquired a little colt who would appear to be shetland or may be smaller. He was rescued from a council estate where he was tied to fence and had kids climbing all over him and torturing him bless him. he seems unaffected and i would age him about 3 yrs.
He is currently in the back garden with one of our cobs and is no bother and very friendly.
But what can i do with him

i dont know if he is big enough to ride but he seems to have a lot of unspent energy. can i lunge him?
i would like him to have a job/purpose but an clueless as to what shetlands are capable of. someone suggested breaking him to drive next year, but he seems so small!!! would he be strong enough? also what does he need to eat. i am presuming no hard feed as he has quite a round tummy - he has been wormed - so just a small amount of haylage?
will his hooves need trimming still or being a hardy breed will they just file naturally? will he need rugging in winter?
he will be getting gelded soon, although he is not coltish at all
also, will he stay in our electric fences

he is in garden at moment which is walled
pic of him to give you an idea of size.
