Using a scoring system from 1 (very thin) to 5 (very fat) based on palpation of the protuberance of the keel, development of the breast muscles immediately alongside the ventral ridge of the keel, and convexity or concavity of the breast muscle contour.
Categorization was done according to quartiles.
Estimated as the weight in grams divided by the average metatarsus measures.
Including ruffled/dirty feathers (n = 6), injury of the eye (n = 2), irritated skin with missing feathers (n = 2), injured wing (n = 1).
Including missing toes (n = 9), entanglement of toes with wire (n = 5), deformity of the wishbone (n = 3), induration on the leg (n = 3), crusted beak (n = 3), scar (hole) on the leg (n = 1).
