Yes, just the ones that you screw into the top of like a Gatorade bottle. They love to drink Gatorade from the end of a syringe and I have dipped their beaks several times in the water bowl but I think they are waiting for me and not drinking on their own. You are right they do make a mess with the dripper but I am still using mostly paper towels and only have the wood chips on one end. The last bag I got of large pine chips is terrible it is a mix of large and crappy little bits. I tried sift out the tiny bits but it scares me and I will just pick up another bag of large from a different vendor. Think I will hook up a dripper, I will watch them and make sure they don't drown..........
