I would advise you to have a youngester and bring on yourself if you have experience.
We had our via the Ausdan Stud in Lampeter, Mid Wales. I believe it is the largest stud in Britain and has some of the top stallions in the country. Lyn Moran is co-owner and also secretary of The Fjord National Studbook of Great Britain. This is the Society website http://www.fjord-horse.co.uk/index.htm
. The Society are very helpful and they will be able to tell you what youngesters are available from members.
You need to take care with imported horses as they often have incorrect papers and registration for pure bred fjords is very strict.
Our fjord was just over 3 years when we bought her and is DNA tested, microchipped and came with full papers. Her temprament is superb. She has been a pleasure to break and back and is now hacking around the farm steadily
