Sometimes, a mare that has never been bedded on straw will eat the straw, especially if it is good quality. To avoid this, it is best to provide the mare with a constant supply of good quality hay. In areas where the weather during foaling season gets very cold, heat lamps are necessary items in the foaling stall. Most healthy foals are hardy and do not need artificial heat. However, when the temperature at night falls below 32 degrees F, even a healthy, vigorous foal benefits from a little extra heat in the stall.
Many mares seem to appreciate the warmth, too.
Even during milder weather, added heat is essential for weak or sick foals because all their energy is needed to stay alive, gain strength, and recover. Most cannot fight the cold as well. Heat rises, so for the lamps to be really effective, the stall should have a ceiling to trap the heat. In cold climates, heat lamps can be put up before the delivery. The lamps should be placed so they are concentrated in about half the stall area.
