An evaluation of the effect of operant feeders on welfare of hens maintained on litter (1994)

Lindberg, A. C., Nicol, C. J.

Abstract

Operant feeding was evaluated as a potential method for preventing feather pecking in laying hens kept on deep litter. The data presented led to the conclusion that operant feeders should be combined with conventional feeders, and birds should be fed mash to decrease the risk of feather pecking.
