The Scottish National entries will already have closed I should think. They always have a set aside penning area for poultry for sale, and you will find that some breeders might take something to sell on the 2nd day, which wouldn't have been there on the first day. I have known friends of ours go home and fetch more pairs of calls ducks because they have been selling so well! As I recall, they always put the exhibitors name address and telephone number in the catalogue, which is great, because then you can contact at a later date a breeder near you.
