Whitetail Deer Gestation Calculator

Whitetail deer have a gestation period of approximately 200 days, which is roughly 6.5 months. During this time, the female deer, known as a doe, carries her developing fawn(s) in her womb before giving birth. This lengthy gestation period allows for the fawn(s) to be born in favorable spring or early summer conditions.

This table provides a concise overview of Whitetail Deer gestation and related information.


  1. How long is a whitetail deer pregnant? Whitetail deer are pregnant for approximately 200 days, or about 6.5 months.
  2. How often does a doe come in heat? Does typically come into heat, or estrus, every 28 days during the breeding season.
  3. Can deer be pregnant in August? Yes, deer can be pregnant in August, as the breeding season for whitetail deer typically occurs in the fall, with fawns being born in late spring or early summer.
  4. How long do fawns stay with their mother? Fawns typically stay with their mother for about 6 to 8 months before becoming more independent.
  5. How long does a whitetail deer stay pregnant before giving birth? As mentioned earlier, a whitetail deer is pregnant for approximately 200 days before giving birth.
  6. Can deer get pregnant any time of year? No, deer do not get pregnant at any time of the year. They have a specific breeding season, typically in the fall.
  7. How does a buck know when a doe is ready to mate? Bucks can detect a doe’s readiness to mate through scent cues and behavioral signals. Does release pheromones when they are in estrus, signaling their receptiveness to breeding.
  8. How long will a buck stay with a hot doe? Bucks may stay with a receptive doe for several hours to a day or more, depending on competition from other bucks.
  9. How long will a buck chase a doe in heat? Buck-doe chases can vary in duration, but they may persist for several hours to a day, especially during the peak of the rut.
  10. What happens to fawns when the mother dies? If the mother dies, fawns may have a reduced chance of survival as they rely on her for milk and protection. However, they may attempt to forage on their own or be adopted by other does.
  11. How far do deer travel from where they are born? Deer can travel considerable distances from their birthplace, especially as they mature. It’s not uncommon for deer to disperse several miles from their birth site.
  12. Do deer adopt orphaned fawns? Yes, in some cases, does may adopt and care for orphaned fawns, especially if they have lost their own offspring.
  13. How far can deer smell human scent? Deer have an excellent sense of smell, and they can detect human scent from hundreds of yards away, depending on wind direction and other factors.
  14. How do you tell if a doe has been bred? Physical signs of breeding in does can include a distended abdomen, changes in behavior, and eventually, the presence of a fawn or visible pregnancy.
  15. How many years can a doe reproduce? Does can reproduce for many years, typically starting around 1.5 years old and continuing for most of their life, as long as they are healthy.
  16. How many does will a buck breed in a season? The number of does a buck breeds in a season can vary widely but may range from 1 to 10 or more, depending on factors like age, health, and competition.
  17. Do Bucks take care of fawns? Bucks do not typically take an active role in caring for fawns. Their primary role is breeding during the rut.
  18. Do deer mate for life? No, deer do not mate for life. They engage in seasonal mating during the rut, and bucks may mate with multiple does.
  19. How old is a buck with 6 points? A buck with 6 points on its antlers is typically around 2.5 to 3.5 years old, but age can vary depending on nutrition and genetics.
  20. What is the lifespan of a deer? In the wild, the average lifespan of a deer is around 4 to 5 years. However, some individuals can live longer, up to 10 years or more.
  21. How can you tell a deer’s age? Estimating a deer’s age is based on factors like antler development, tooth wear, body size, and other physical characteristics.
  22. What do deer do right before giving birth? In the days leading up to giving birth, does often become more reclusive and may seek out a quiet, secluded spot to give birth.
  23. What time of day do deer mate? Deer are crepuscular animals, meaning they are most active during dawn and dusk. Mating can occur at any time during these periods.
  24. How many deer can a doe give birth to at once? Does typically give birth to one to three fawns at a time, although twins are most common.
  25. Can a yearling doe breed? Yes, in some cases, yearling does can become pregnant during their first breeding season.
  26. How do fawns know to stay hidden? Fawns instinctively know to stay hidden and lie still when their mother leaves them. This behavior helps protect them from predators.
  27. Can you tell if a fawn is male or female? It can be challenging to visually determine the gender of a fawn without close examination. Typically, males have small, button-like bumps on their heads where antlers will eventually grow.
  28. Will a buck breed a doe more than once? Yes, a buck may attempt to breed a receptive doe multiple times during her estrus cycle.
  29. Will a buck chasing a doe come back? Bucks may continue to pursue a doe in estrus for an extended period, but eventually, they may return to their usual activities if unsuccessful.
  30. Will a doe call bring in a buck? A doe’s vocalizations, known as bleats, can attract bucks during the rut, as they may be seeking out receptive does.
  31. How far does a whitetail buck travel during the rut? Bucks can cover several miles while searching for receptive does during the rut, but the distance can vary widely.
  32. Do big bucks stay in the same area? Big bucks may have established territories, but they can also roam widely during the rut in search of mates.
  33. What is the lockdown phase of a buck? The lockdown phase refers to a period during the rut when a buck stays with a receptive doe, limiting her movements to ensure successful mating.
  34. What time of day do Bucks chase does? Bucks may chase does at any time during the day, but it is more common during the early morning and late afternoon.
  35. What is the lockdown phase of the rut? The lockdown phase is a stage during the rut when a buck remains with a receptive doe to mate, often keeping her in close proximity.
  36. Can doe estrus scare deer away? The scent of doe estrus can attract bucks, but it is unlikely to scare deer away unless they detect danger associated with it.
  37. Will fawns survive if you shoot the doe? If a lactating doe is shot and killed, the survival of her fawns depends on their age and ability to forage on their own. Very young fawns may have a lower chance of survival without their mother.
  38. Do baby deer cry for their mother? Yes, fawns may emit distress calls if they are separated from their mother or feel threatened.
  39. Do deer stay together as a family? Deer do not form family units in the same way some other animals do. Fawns typically stay with their mother for a while, but deer are generally solitary or in small groups.
  40. Do deer stay in the same area their whole life? Deer do not typically stay in the same area their whole life. They may have home ranges and disperse to new areas as they mature.
  41. Do deer sleep in the same place every night? Deer do not sleep in the same place every night. They often bed down in different locations within their home range.
