Whitewashing for inside chicken house. "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."
Graduated design. There's plenty of room for them to spread out but no one is sitting underneath another hen and in the direct line of fire!" Easy to clean out manure and no need to sequester the birds in the run while you do it.
