My four chicks are about 3 1/2 weeks old, and still growing nicely in a very large dog crate in the laundry room. However, I'm finding it impossible to keep their water clean, it is a small plastic "chick" water container, an inverted "jar" style with a tray at the bottom. They poop and walk in the tray portion all the time. How do you all solve this? Could I train them to use a water bottle (such as a rabbit variety) at this age? I don't see a way to hang the current little container I have, nor do I have room to put a large hanging water dispenser in there for them.
