Some people have no easy access to bales so cubes is an option when you have no other options.For me part of the benifit of alfalfa hay is the time it takes the flock to scratch a flake apart and pick up all the leaves. This takes time. In the winter when they can not get out, this gives them something to do besides picking on each other. Im not sure a water soaked cube will have the same effect. Maybe if i only had 3 or 4 birds it would work.
