Rabbit Gestation Calculator

Whether you are a hobbyist rabbit owner or a professional breeder, the Rabbit Gestation Calculator is an invaluable tool for managing rabbit pregnancies effectively.

By accurately predicting the kindling date, you can provide the best care for your doe and her litter, ensuring a successful and healthy kindling process.

The average gestational length for a rabbit is 31 days, but it can range from 28 to 35 days. This variation makes it challenging to pinpoint the exact due date without a tool like the Gestation Calculator.

Rabbit Gestation Calculator


Let’s perform a calculation using the Rabbit Breeding Calculator:

  • Mating Date: March 1, 2024
  • Average Gestation Period: 31 days

By inputting these values into the calculator, the estimated kindling date would be March 31, 2024.

Mating Date: March 1, 2024
Average Gestation Period: 31 days
Estimated Kindling Date: March 31, 2024

1. Domestic Rabbits

  • European Rabbit: 30-33 days
  • New Zealand Rabbit: 28-35 days
  • Californian Rabbit: 28-32 days
  • Flemish Giant Rabbit: 30-35 days

2. Wild Rabbits

  • European Rabbit (Wild): 28-33 days
  • Cottontail Rabbit: 26-30 days
  • Jackrabbit: 30-42 days

3. Other Rabbit Species

  • Marsh Rabbit: 30-37 days
  • Swamp Rabbit: 30-35 days
  • Riverine Rabbit: 28-32 days

When using the Bunny’s Breeding Calculator, it’s recommended to input the breed-specific or species-specific gestation period, if known, for the most accurate estimation of the kindling date. If you’re unsure about the exact breed or species, you can use the general average of 31 days as a starting point.

How to Use the Rabbit Gestation Calculator

  1. Enter the Date of Mating: First, input the date when the doe was successfully mated with the buck. This date is crucial for accurate calculations.
  2. Choose the Gestation Period: The calculator typically uses the average gestation period of 31 days. However, you can adjust this value based on your rabbit breed’s specific gestation range or your own experience.
  3. Calculate the Due Date: After entering the mating date and gestation period, the calculator will provide you with the estimated due date or kindling date.

Benefits of Using the Bunny Gestation Calculator

The Rabbit Gestation Calculator offers several advantages for rabbit owners and breeders:

  1. Accurate Due Date Prediction: By accounting for the variation in gestation periods, the calculator provides a more precise estimate of the kindling date compared to relying on the average gestation length alone.
  2. Preparation for Kindling: Knowing the expected due date allows you to prepare the kindling box or nesting area in advance, ensuring a safe and comfortable environment for the doe and her kits (baby rabbits).
  3. Monitoring the Pregnancy: The calculator helps you keep track of the pregnancy progress, enabling you to watch for any signs of complications or distress in the doe as the due date approaches.
  4. Record-Keeping: The calculated due date can be recorded in your rabbit breeding logs, providing valuable data for future reference and tracking purposes.

Important Questions

How many weeks does a rabbit stay pregnant?

Rabbits typically stay pregnant for 4 to 5 weeks. The average gestation period for rabbits is approximately 31 days, which translates to about 4 weeks and 3 days.

What is the longest gestation period for a rabbit?

The longest gestation period for a rabbit is around 35 days. While the average is 31 days, some breeds or individual rabbits may carry their litters for up to 5 weeks.

How do you calculate a rabbit’s pregnancy?

To calculate a rabbit’s pregnancy, you need to know the mating date and the average gestation period for the specific breed. Here are the steps:

  1. Note the mating date when the doe was successfully bred.
  2. Determine the average gestation period for the rabbit breed (usually around 31 days, but can vary from 28 to 35 days).
  3. Add the gestation period to the mating date to calculate the estimated kindling date or due date.

For example, if the mating date was March 1st, and the average gestation period for that breed is 31 days, the estimated kindling date would be March 31st (March 1st + 31 days).

Do rabbits give birth on day 28?

While it is possible for some rabbits to give birth on day 28 of their pregnancy, it is considered early and not the norm. The average gestation period for rabbits is 31 days, with a range of 28 to 35 days.

Giving birth on day 28 would be considered preterm and could potentially lead to complications or underdeveloped kits (baby rabbits). However, in some cases, healthy rabbits may naturally give birth within the earlier end of the gestation range, around day 28 or 29.
