Does anyone know much much water a deer drinks in a day, or a week? The reason I ask is because of the cold weather coming. Last year we got a terribly cold spell that last for about a month. All our ponds froze up and at some points the river was even froze in some places. I’m curious of what deer do in times like these. I know farmers run water troughs with heaters in them for their cattle, does anyone do the same for deer? Any other tips?
