Thank you Ron, that's so nice of you to say. I don't like to say best. There are several serious breeders of SGDs that are working hard to improve them.
I agree. If you are looking for Dorkings that are going to win at shows, they don't exist. Or, very few exist and the owners of them aren't going to let them go. There are breeders who are breeding toward the standard and making progress, improving every year. The term "show quality" means different things to different people. Some breeders think it means birds that don't have disqualifications. Those exist.
The Dorking was neglected by serious breeders for a very long time. The old breeders either died or stopped breeding them. New breeders bought inferior hatchery stock because that was the only place to get them. That's why Dorkings that meet the standard are so hard to find at this time. It's not a question of money.
This is also the wrong time of year to get birds from good breeders. Go to the Dorking Club website. Contact breeders and ask to get on their waiting list. If you don't have patience, this is not the breed for you. If you are on Facebook, join the Dorking groups there. That will help in your search.
