Standard light bulbs or fluorescent tubes in each stall will do the job. As with anything electrical in a barn, make sure that cords and wires are well out of horses' reach. Foaling stalls can be either specially constructed, or converted by removing a wooden partition between two regular stalls. In either case, a foaling stall should be located toward the center of the barn, near the office or a place where the foaling mare can be observed unobtrusively by the farm staff. Hygiene is of paramount concern in a foaling stall, so it should be constructed of materials that make it easy to clean and disinfect.
Floors can be coarse asphalt or limed clay, and thickly bedded.
Foals born in the early winter months are susceptible to hypothermia, so concrete floors, which are cold and unyielding, should be avoided. Look, instead, for phenolic compounds such as Lysol or Tek-Trol. Use according to the manufacturer's directions, scrubbing down the foaling stall before and after each foaling. A stallion is usually a bigger animal, as well as a little more rambunctious, so he needs a little more room to move around. In addition, most stallions get limited turn-out, usually on their own in a paddock isolated from the sight of mares or other stallions.
