I ordered them in April last year. I think their Dorking flock was affected by the AI earlier this year, so you might have to wait until next year regardless… You can put in an order around the beginning of November usually, that way you can get your preferred birds and date for 2023. 😁
McMurray had Silver Dorkings too! I got my Bielefelder and Dorking from them! Great birds, very chill and easy to handle. The Dorkings eggs are little though, but she is a very regular layer. My Bielefelder lays a ton of big speckled brown eggs.
