I have two small plastic waterers (is that the correct word?) for my 5 chicks. The problem I'm having is that they get ridiculously dirty and full of shavings (and worse) really quickly. I've tried elevating them which works somewhat but I was wondering if anyone has any suggestions about watering in a way that will keep the water cleaner. I'm looking for a better system especially as the cold winter weather approaches. Thanks for any thoughts.
