Whitewashing the chicken coop - Classic lime whitewash disinfects, repels insects, and preserves by sealing surfaces and wicking up water. It dries to an opaque white that beautifully reflects light to brighten up dim spaces.
This is how I keep my water from freezing in the winter. Only I use cinder block. Cinder block heater & water warmer - light bulb inside cinder bock covered with a stepping stone & water container set on top won't freeze.very clever idea!
