The plot thickens!
Ive had the droppings of both ponies tested for fluke. Interestingly, Hamish, who has lived here since February, is negative but Katalin, who only came to us about 6 weeks ago, is positive. My vet believes that she probably came to us already infected but of course now both ponies will have to be treated for fluke, as will all the lambs when they arrive ( unless they have already been done).
I now have the horrible task of using Fasinex, which is unlicensed for horses and can be highly toxic to them. Both Westgate and my vet ( who has spoken to a specialist at The Dick) say I cant leave Katalin untreated, and Hamish has to be treated too as he might also pick it up

Apparently I just have to keep my fingers crossed that they don't have a bad reaction to the Fasinex.
Ive been given the telephone number of the Prof in Edinburgh and Im going to talk to him on Monday....everyone is being very kind but Im so worried. Especially for Hamish who is fluke-free at present ( as far as we can tell).
Its going to be a very expensive job too as we are now facing 6 weekly fluke counts until all the grazing animals test negative for 3 months: it might well break the bank
