No, only those already in the Standard can win those.
Winning AOV is as far as non-standard or non-approved bird can go.
Take for example both the Lav. Orp and the Mille Fleur Cochins - they can only be shown as AOV until accepted by the Standard. To be accepted by the standard, the bird must represent both the "outline" of the bird and breed true both in body style and color pattern plus be shown for 5 years.
I should clarify - at least this is what I am learning - I have not shown chickens in many, many years (did when I was very, young - kindergardenish).
Gaited???? Where are you? You should be answering these questions........He must be busy as a bee getting ready for tomorrow.
