At what age do you raise the water up higher so it stays cleaner?
I just raised to be neck high as they grew.
I had mine on a 1" board the first day. I raised it the first week to a 2x4 and now I have them hanging 5" up. Hanging them was the best yet. I never have to clean out the waterer anymore...Just wash it frequently and refill.
When they 'scratch' in their bedding it will fly right into the waterer so keeping it clean is a must.
