A once a day feeder!  This is the largest model we have.  Round just like the other models, and can be used anywhere - in a stall, paddock or outside in the pasture.  Does NOT have to go in a corner but fits neatly into one if required.  Drain plug for easy clean up or when soaking hay.  Holds 4-5 average size biscuits which lasts most horses 24 hours.  NOT AVAILABLE WITH A LID/WATER TROUGH and only comes with 3.5" & 4" Restrictor Pans.
