I've got 2 week old chicks and one of them, keeps hopping on top of the waterer. Is there anyway to make her stop? I've hung papertowels through the top of the cage to sort of block her, but I don't know how much that is going to help or prevent her from continuing. I'm thinking of fashioning a dunce hat out of tinfoil and putting that on top, but I'm not sure that would work and think if they get to it, it may not be good for them.
