Can Deer Have More Than One Baby?

White-tailed deer, the most common North American species, typically have one to three fawns per year per mature doe. Mule deer, common in the western United States, usually give birth to a single fawn in their first breeding year and twins thereafter. Red deer, native to Europe, northwest Africa and North America, usually produce one to three fawns per year. Roe deer of Europe have a similar reproductive pattern. Fallow deer, which can be found in Europe, Asia Minor and North America, usually produce only a single fawn per doe but can have twins.
