All summer we had a drip drinking system installed inside our coop and never had a problem with moisture. Now the drippers are constantly releasing water leaving frozen stalagmites below on the cold days and soaking the sand on the not so cold days. I tried cleaning and replacing drippers and have finally given up and started filling old 2 gal metal waterer. I still have a lot of wet/ frozen sand inside, which I know is not good. Any help on what I could do would be appreciated.
