Four or more concentric rings are vertically separated from each other by placement along the vertical axis of four support members. The circular construction accommodates hay bales for feeding animals. The openings between the concentric circles are defined by their placement along the vertical axis of the support members. The structure may be comprised of one or more sections that may disassembled for relocation. Alternatively, the system may be of a unitary construction.
