A method to evaluate the walking ability of chickens. We use the system developed by Kestin et al. 1992 which has 6 categories, as follows:
0 – No detectable abnormality, fluid motion
1 – Slight defect. Difficult to define.
2 – Definite and identifiable defect, but it does not hinder movement
3 – An obvious gait defect that affects the broiler’s ability to maneuver and accelerate
4 – A severe gait defect. The broilerChickens kept for meat production. Fast growing breeds can reach a weight of over 2 kg at 5 weeks of... will only walk a couple of steps if driven before sitting down
5 – Complete lameness. Either cannot walk or cannot support weight on the legs.
