I use a water bottle for my parrot. It keeps the water clean and no mess in the cage. My 3 week old chicks keep getting poop and pine chips into the waterer. Just out of curiosity, I decided to hang a water bottle. Sure enough after a few minutes, the three buttercups started investigating. And they figured out how it works. I am so proud of them. Later, I noticed they had taught some of the other chicks how to do it. It would be great if I knew that all of them knew how to use it. I won't risk it by taking their regular waterer out. But maybe over time, they will all learn to use the water bottle. That would be so fantastic.
