Counting from records

On a date, tick Count from records for an option, and what’s for sale is worked out from your records instead of a number you type.

• Chicks: eggs set for that date × fertility × hatch of fertile eggs. Your own rates are used once you have three results for the species in the last year; species defaults until then. Candling tightens the count, and a hatch result replaces it with the real number.
• Nucs and packages: the colonies you plan to split for the date × split success.
• A safety margin holds back part of what’s only projected. Real hatch counts aren’t cut.
• Straight-run and sexed options share one pool; each sexed option can take at most half.

Records are kept as a history. A correction is added as a new record, and both stay visible.
