we raise bucket calves. right now we have individual 2 gallon buckets, looking for a better system. a guy was telling me the other day, that i could make automatic waters using 6 inch. pvc pipe an cutting holes that calves could drink out of. with an automatic float valve inserted in pipe. with clean out on each end. then fasten the lenth of the pens. of coures level wondering if anybody had any better ideas before i do this. thanks hillside
