Hi there, We have just 5 hens and presently use 2 water containers, 1 qt and 1 gallon. I was thinking of getting a 3 gallon water container for when we are on vacation until it didn't seem to make much sense to use a larger container. As many of you have come to discover chickens are messy critters and kick up dirt into their waterers even just after 1 day. Even if the waterer is hanging up above the ground or up on a higher platform the water gets dirty fast. If the dirt isn't from the hens kicking it up into the water it still gets dirty just from their dirty beaks in a very short time. I find myself changing the 1 gallon waterer before it's even half empty due to the dirt collected in the dish. So getting a 3 gallon waterer would get dirty just as fast as the smaller ones so does it make sense to size up? What do you do to keep the waterer clean and fresh other than changing the water every other day? Thanks for your feedback!
