Calendar use

Turn a breeding date into farm tasks

A lambing calendar is useful when it helps the farm prepare work before pressure starts: supplies, observation, lambing records and post-lambing follow-up.

Before lambing

Prepare supplies, clean areas, review ewe notes and increase observation before the expected window.

During lambing

Record actual lambing date, lamb count, lamb sex, tag numbers, problems and assistance.

After lambing

Check ewe and lamb condition, treatment notes, weights and follow-up tasks after the event.

Connected records

A calendar helps planning. Records explain what actually happened.

Expected lambing dates are useful, but the farm also needs the actual lambing outcome, lamb identity, ewe notes, health events and pedigree context.

HerdDeck keeps those events connected to animal cards and reports instead of scattered in separate notes.

  • Prepare aheadUse calendar dates to prepare supplies and observation.
  • Record actual eventsExpected dates should be replaced by actual lambing results.
  • Review laterLambing history supports breeding, culling, replacement and sale decisions.

Next step

Move from lambing plans to connected ewe and lamb records.

HerdDeck Shepherd connects breeding, lambing, animal cards, treatments, pedigree, feed, finance and reports so lambing plans become part of the flock history.
