mechanical pluckers for ducks, turkeys & chickens

[kimb]

Is there a mechanical plucker that will work on all poultry, including ducks?

Was hoping we could make or find a plucker that will effectively pluck all the birds we raise (including muscovy ducks, chickens & turkeys). I haven't been able to find much on the effectiveness of plucking ducks with a mechanical plucker, and people that I ask all hand pluck their ducks.

Thanks !
