Feathers can be removed either manually or in a tumbling machine. Both methods require the feathers to be first loosened by submerging the slaughtered bird in hot water. Manual plucking involves pulling out the larger feathers then removing the down with a rubbing action. Automated plucking machines use rubber posts protruding from the inside of a spinning drum to pull the feathers from the bird. This process takes less than 30 seconds, whereas manual plucking typically takes several minutes.
