Legs are one of the key elements in creating balance within a bird and within a breed. As mentioned in previous articles, every aspect of an individual bird plays a specific role in vigor, health, production, and overall balance. When one key point is off, it can create a domino effect that throws everything else out of alignment.
Legs are often a critical point that gets overlooked by breeders of all levels - hobbyists and exhibition breeders alike. Color and type are easier to assess, so we tend to focus on them while dismissing the true foundation of the bird: the legs.
“Proper leg structure in poultry is critical for mobility, longevity, and overall productivity; structural defects can lead to lameness, reduced feed efficiency, and compromised reproductive performance, making it a key selection criterion in any responsible breeding program.”

Selecting breeders with correct leg structure supports not only production, back and tail structure, and overall balance, but also helps prevent common issues such as slipped tendon and splayed leg.
First and foremost, when viewed from the front, legs should be relatively wide-set and come straight down from the center of the body. This creates a stable, well-balanced frame.
The ACBA’s SOP calls for lower thighs to be short, thick, and muscular, sloping slightly into the hock, with shanks of medium length.
In the visual provided by breeder Mary Lavook, you can clearly see what the eye should be drawn to when evaluating proper leg structure.
When the SOP calls for “medium length” shanks, we should be looking for a rectangular profile rather than a square one. We want enough length to maintain balance and proper carriage - but not so much that the bird appears lanky, and not so little that it appears squat. The goal is balance, right in the middle.
Unfortunately, we often see birds with knocked knees or bowed legs. These structural issues can be passed on genetically and can quickly take over a breeding program, leading to problems that go far beyond aesthetics.
There is a reason we have the APA and SOP in place. These standards are not simply about appearance - they exist to guide, restore, and preserve our breeds for future generations.
