I've been wondering how this works on chickens. Drill plucker
There is the wiz bang chicken plucker that is amazing. Also we use cones to do the deed. It is so much more humane as humane as this sort of thing is. You can find plans on line by googling the wiz bang chicken plucker. You will find also that you can buy one already put together.
we got to see said wiz bang plucker in action this weekend.... I have to say I am ABSOLUTELY impressed. It is much thriftier to make one yourself.... but you can purchase one that is ready to plug in and go.
