you could try it but i cant imagine it would work too well. i have actually trained one of my iguanas to drink out of a rodent water bottle but she still prefers her water bowl and the mistings, sometimes she will get frustrated that so little water comes out of the bottle so she will bite the end which i kind of worry about since it is metal. the easiest thing to do is just squeeze the bottle so that they can see the water dripping out of it, hopefully he will learn to lick the bottle for water to come out.
the one thing i have always wondered was, how do rodents know how to drink out of bottles, they dont need to be taught and i always thought that was strange that they instinctually do it, like there are little water bottles tacked nicely to trees in the woods that they would naturally drink from lol.
Good luck with the beardie.
