Broiler/meat-bird gait score (Bristol 0-5 scale) — Bristol, England.

This standard's own scoring instrument carries the name 'the Bristol scale' -- the 0-5 gait-scoring system named for Bristol, England, home of the University of Bristol's veterinary school, this library's already-verified real institution for UK farm-animal welfare research (the AssureWel welfare-outcome protocol this library's laying-hen standard cites was also built there). Honesty limit stated directly: this tile connects to the scale's own namesake city and its real, verified veterinary research institution, not a confirmed personal affiliation of Kestin/Danbury with that specific university, which was not independently verifiable this wake -- a distinct, more cautious connection than this library's existing Gainesville tile (the modern US broiler industry's own vertical-integration origin city).

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

A dated flock gait-score round: sample size/method, per-bird Bristol 0-5 score, contact-dermatitis welfare signs noted, flock distribution and share scoring ≥3 recorded and compared to the prior round, with every ≥4 or pain-signal bird routed

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• A flat, unobstructed walking area (about 2 m) inside or beside the coop/run
• The published Bristol 0-5 gait-score descriptions/photos
• A sampling plan and tally sheet
• Prior audit scores for trend

Steps

1. 1. State the sample: whole flock for small backyard keeps, or a representative sample for larger meat-bird flocks; record the number scored.
2. 2. Encourage each sampled bird to walk about 2 m across a flat, unobstructed area without chasing or startling it; observe from the side.
3. 3. Assign the Bristol 0-5 gait score per bird from the published descriptions: 0 (normal, agile) through 5 (unable to walk/stand); do not average — record each bird's own score.
4. 4. Note visible contributors while scoring: hock burn, breast blisters, or footpad dermatitis (contact-dermatitis welfare signs that often travel with poor gait).
5. 5. Record the flock distribution (count per score 0-5) and the share scoring 3 or above.
6. 6. Compare to the prior audit; a rising share of 3+ scores is a management/genetics flag, not something to wait out.
7. 7. Route findings: any individual bird scoring 4-5, or showing pain signs (reluctance to move to feed/water, isolating), separated and routed per the decision rules; flock-level rising lameness routes to a management/genetics review.

What counts as done

• Sample size and sampling method stated; every sampled bird scored individually 0-5 on the Bristol scale
• Contact-dermatitis welfare signs (hock burn, breast blister, footpad dermatitis) recorded alongside gait score
• Flock-level score distribution and the share scoring 3 or above recorded, compared against the prior round when one exists
• Any bird scoring 4-5, or showing pain/isolation behavior, routed to a veterinarian or humane on-farm euthanasia per the decision rules

Proof is measured against these, not judged by taste.
