Can rabbits use poultry watering nipples?

[Cottie]

I have a plethora of watering nipples (bought in bulk). They have a post that gets depressed by the beak, then voila, water!

So, can rabbits use these? My concern is the post would cut their tongue.

I have wondered this, too, as I have extras myself.

They are designed for the chicken to drink from them from below. Not sure if it would work out for rabbits, but I do wonder.

Yeah...and they leak if you put them in at more than a slight angle.

I found some rabbit watering nipples on Aliexpress. A dern bit more convenient than the poultry nipples, since it connects directly to piping (rather than threading into PVC). I may investigate this more for the tractor, but I'd still prefer to use my poultry waterers.
