I'm not too sure now. Has any one ever tried? Some times the chickens protest but they submit to me so it's not that bad once you get them in the water. Accept Red Nugget. If you can catch him he voices his opinion loudly. And often beets you flapping his wings. He usually gets out of it.
My ducks bathe themselves. Ducks should always have a tub to wash in because there faces get muddy around the nose and eyes and can cause infections. I used to just fill an ice cream pale and then they can wash there faces and thats enough for them.
