Along with my heated water buckets, I put the bucket in a tire and pack hay or straw around the bucket to keep it from freezing in really really cold weather; I live in Northern Mn, so even with the heated buckets, my goatie buckets freeze slightly...ACV also helps keep the water from freezing as much...
I use hay bags (not the net kind) to keep my goat's hay off the ground...I put them up a little higher than chest level so they can't get their legs caught in the nose hole (they are horse hay bags). It keeps their hay clean, and off the ground...which my goaties appreciate! AND I appreciate that they can't step on it and stick their noses up at it in discust and not eat it!!
