Q: i have question about the cup , is it over spill due to keeprefilling on its own? used product even chickens were not drinking and cusz overspill

I found that the cups need to be fairly level and that fixed the problem for me.

Q: Duck nostrils under water with this?

Ducks can use this automatic water cup

Q: can this cause the dirty water to be syphoned up into the clean water?

I have not tried this vendor's product yet. In my experience with similar product from other vendors, the water is not syphoned back into the clean water, it is the main reason I use them. The water in the container is always clean. the cup gets dirty and has to be clean daily.
