Cause of Cannibalism and Feather Picking

Correct Answer: Fibre-free diet

Cannibalism (eating of own species) and feather picking in poultry are primarily caused by feeding a fibre-free diet. The recommended crude fiber level in chicken diet is 3–4%.

Why Fibre Matters

• Adequate dietary fiber keeps birds occupied (longer feeding time).
• Fibre-free diets lead to boredom, frustration, and redirected pecking behavior.
• The problem is more common with pelleted and crumbled diets since pellets are consumed quickly, leaving birds with excess time and energy.

Other Contributing Factors

• Overcrowding
• Bright white light (solution: use red light)
• Nutritional deficiencies (protein, sodium)
• Prevention: debeaking at day-old, using red light, providing adequate space
