(e) Provision of unbalanced feeds to birds, including minerals and proteins in the
poultry rations.

Control measures of cannibalism and feather pecking
(a) Provision of enough floor space according to the bird age, types and rearing
systems.

(b) Reduction of light intensity by using dim light sources or orienting the building
such that the light does not hit the long side of the building.
(c) Provision of sufficient feeders and drinkers according to the recommended ratio

to the available floor space and birds.
(d) Provide birds with enough and balanced feeds according to their physiological
and production requirements.

(e) Use appropriate control measures against external parasites such as thorough
cleaning of the environment, poultry houses, feed and water facilities. Fill floor
and wall crevices and apply recommended parasiticide to eliminate parasites.
(f) Ventilate the houses to bring in fresh air and remove foul smell by allowing
enough air in the poultry houses.

(g) Make the birds busy by hanging up bunches of greens such as vegetables or

edible tree leaves.
(h) Always isolate pecked birds to prevent further pecking or death of the birds
and treat the pecked birds.

(i) Debeak the birds as a last option when other means have failed. Never debeak
free range birds as this will make them fail to pick feeds.

Egg eating: Egg eating starts accidentally when birds find a broken or soft shelled
eggs laid without a shell. This habit spreads rapidly if measures to stop it are not
taken. The habit is an indicator of a poorly managed flock. Figure 6.7 shows egg

eating in layers.
