Re: awful day - my boys are for sale ;-(
Oh gosh what awful news - but like the others have said is there anyone who could share or loan them?
As Mel has commented, horses aren't selling well as people don't have the money to buy, but may very well be happy with forking out a little to share one.
I think you've said somewhere you have your own field - is it actually yours or do you rent? If it's yours is it big enough to rent some of it out to someone else, and are you registered with the Rural Payments Agency who will pay you a certain amount each year depending on acreage?
I do hope you can find a way of keeping them, I'd be devastated if I had to lose mine.
Keep cheerful, and keep us posted.
