The aim of this work is to design and fabricate a small scale de-feathering machine and investigate into the optimal operational parameters for de-feathering. The fabricated de-feathering machine has its electric motor placed by its side for easy coupling, detachability and prolonged life span of motor. It has a door by its side for easy removal of the carcass. The materials used for the fabrication of the de-feathering machine were carefully selected to ensure minimal damage to the carcass.
