ooh, good luck finding your black highland, Karen!!!
I was at Clitheroe carriage sale the other week, and they were selling poultry on the same day. Plenty of ducks and geese around, but only had a quick look so cannot say if they had any indian runner ducks. They do a sale there on Wednesday evenings - 5pm I think, fur and feather. Usually well attended and plenty of birds. Just a funny time for us to go especially in winter, with evening feeds to do.
