Could be...except everywhere I searched consistently called the long legs OEG or OEGB ~ even good ol' Chickenlandia video . Show breeders are trying to confuse me teehee. So much stuff has been introduced since we 1st started backyard chickens ~ it was about the time Greenfire Farms in Florida started vigorously importing all the new foreign countries' breeds & variants..I stopped keeping up ~ especially after the Breda Fowl import failures. But that's ok...I'm happy staying w/our standard Silkie bantams that are hardy as cold or heatwave survivors that lay the largest of bantam eggs & can't fly out of our yard!I think those are those modern game birds. I think that’s what you’re thinking of.
