We have one, now 19 year old Exmoor Pony. (we had 4 at one stage!) and quite honestly he is absolutely no trouble at all. We have a stable,small yard,and a 1/2 acre paddock with field shelter. He lives out in the summer, in the winter, he's in at night, out in the day. Obviously he has to be mucked out, hay and feed provided, hooves attended to, wormed and anything else that rears its head. (Ragwort!) He is a pretty placid boy,but we take nothing for granted. He has in fact given us enormous pleasure over the years and still does. I would love a donkey companion for Merlin but they can be a bit noisy!! My only advice for equine care is to get into a routine as much as possible on a daily basis, a bit like a baby! Then the general care ceases to be a chore. We have different routines for summer,when it's just a case of checking water, de pooing and saying hello, to winter when more effort is needed! We are lucky in that our garden leads into the paddock, and our stable block is literally outside our back door, this of course does make care easier.
