I recently ordered 5 chicken drinking cups. They are basically little orange cups with a lever inside. When the chickens move the lever with their beak, water comes out. It's actually pretty nifty and I rigged up a pvc waterer to screw them into. The only problem is that they haven't figured out how to make the water come out. I have taken out their other waterer to try to make them pay more attention to it. I have been filling them with my finger frequently throughout the day but school is coming up and I won't be around to do that. Any ideas?
