Practical Example

Let’s say you bred a doe on March 1, 2025 and use the default gestation length of 150 days.

• Breeding Date: March 1, 2025
• Estimated Due Date: July 29, 2025
• Minimum Due Date (Early): July 24, 2025
• Maximum Due Date (Late): August 3, 2025
• Days Pregnant (Today): 50 days (if checked on April 20, 2025)
• Days Remaining: 100 days

This information helps you prepare for kidding season—ensuring your doe gets proper nutrition, housing, and care.
