I use both bucket methods! my whole grains are in a double bucket so I can easily drain them. My game bird starter/ground feed for chicks I keep in a single bucket and must mix thicker so I can scoop it straight into their feeders. I think it's whatever you think will work best for you? I know some poeple have several buckets going, and they use up one then re-start it and go on to the next. I use mine like a sourdough starter, but I have much fewer birds!
