Areas of Routine Violations (cont'd)
A 1990 study found a 44 percent increase in newly broken bones in hens post-shackling (Gregory and
Wilkins, 1990), reflecting the stress and trauma caused by this practice.
Turkeys are at particular risk, as some may weigh up to 28 kg (60 lbs) when slaughtered. These birds
weigh 10-15 lbs more than lambs, yet it is illegal according to Canadian slaughter standards, to live-
suspend a conscious lamb for slaughter (even for halal or kosher ritual killings).
"Shackling: The force of this hanging procedure [birds are hung upside down and
clamped in the shackles at their ankles on a conveyer belt] causes pain because
the affected bone surface is enriched with pain receptors causing over 90
percent of birds to flap their wings due to pain. There is enough scientific
evidence to suggest that shackling live birds increases the prevalence of
dislocated joints, broken bones and muscle bruising in conscious birds."

"Hanging upside down on metal shackles is a physiologically abnormal posture
for all poultry, including turkeys and is painful and distressing. Under this
situation, compression of their legs by metal shackles is known to be an
extremely painful experience to all poultry, especially heavy turkeys." (Dr. Mohan
Raj, Senior Research Fellow, Department of Food and Animal Science,
