ARSD 41:09:13:02. Bird marking required

Except for partridge and quail, all game birds released or used in any event or activity related to sporting dog training or field trials must be marked by wing pinion or must have one front toe or one hind toe on either foot removed back to the first joint including the nail, before the birds are six weeks old. An anti-pecking device affixed to the bird before it is six weeks old and worn by the bird until it is at least 15 weeks old is acceptable in lieu of toe clipping if the anti-pecking device leaves a permanent, easily identifiable mark.
