breaks of feather pecking and cannibalism start, they are difficult to control because the behaviors are socially transmitted among birds in the flock; therefore, it is best to prevent their occurrence through early intervention." "Providing floor-housed chickens with cover in the
form of overhead vertical panels has been shown to
improve pen usage, increase resting and preening be-
haviors, and decrease the number of times that birds
disturb one another " "provision of shelters and canopies on
free-range areas has been found to increase range use
by chicken" "Other constraints on enrichment are
related to facility design, cost, sanitation, ease of man-
agement (including the amount of time and effort that
