My waterer is a little bigger, but I'm going to try to hang it like yours Neuport. The Marans love to roost on top of it and walk in it.I didn't have much luck when I tried putting them up on blocks of wood. I think it works best when they have to reach slightly to put their beak in. For me the waste stopped when I hung them. I agree it would not work as well if the birds vary a lot in size.
