Lamb Gestation Calculator

Calculate your ewe’s lambing date with our Lamb Gestation Calculator. Accurately predict birth dates based on mating date, breed, and fetus count.

Ever stared at your pregnant ewe and wondered, “When is she actually going to give birth?” If so, you’re not alone. Sheep don’t come with due-date reminders, but don’t worry we’ve got you covered!

The Lamb Gestation Calculator makes tracking your ewe’s pregnancy simple. Sheep carry their lambs for about 147 days (roughly five months), but just like humans, some deliver a little early or take their sweet time. With this tool, you can predict lambing dates and prepare in advance because nobody wants to be caught off guard when a lamb decides to make a surprise entrance!

How to Use the Lamb Gestation Calculator

It’s as easy as counting sheep (but way more exciting)!

  1. Enter the Mating Date – The day your ewe was bred.
  2. Select the Breed – Some breeds have slightly different pregnancy durations.
  3. Consider Litter Size – If she’s carrying twins or triplets, she might go into labor early.

Hit calculate, and voilà! You’ll get an estimated due date, plus a range for possible early or late deliveries. No more guessing games!

Figuring It Out Manually (For the Old-School Farmers)

If you’re the type who prefers mental math over machines, here’s a quick formula:

Lambing Date = Mating Date + 147 Days

Example:

Let’s say your ewe got cozy with a ram on January 1st.

  • Expected due date? May 28th
  • Carrying twins? She might pop around May 25th.
  • Running late? If she’s still lounging on June 2nd, you might have an overdue diva.
