I did not read all of the posts, so this might be a duplicate answer.
I went to our local building supply center
(Menard's) and bought a mud mixing boat.
that is the contractors' term for it.
what it is , is a rectangular rubber tub.
about 2 feet x 3 feet by about 8 inches deep.
It holds about 15 gallons of water. I fill it daily. the next day I dump the slab of ice out and put fresh water in it again..
no need to heat it because the water is above freezing .. I used this for geese for over 10 years.. the tub is still in good shape.
I have watched geese splash in it when the temperature was below -20F. the water drops froze and beaded on their backs and rolled off like BB's. they loved it.
by letting the water freeze in the tub it prevented ice on the ground if when you dumped the water..
by the time they got finished bathing and splashing, most of the water was out of the tub so there would be only about a 3 inch thick slab of ice in the tub.
I just tipped the tub upside down and gently thumped the bottom with my foot and the whole piece drops out whole..
