Explore the numbers behind your hatch—and what a mathematical estimate can (and cannot) tell you about future males and females.
1. Review a completed hatch
Enter actual counts. For example, if 12 eggs were set and four chicks hatched, the hatch rate of eggs set is 33.3%.
A candling observation, not proof of every egg's fertility.

PERSONAL HATCH SUMMARY
Your hatch, explained
—
Hatch of eggs set
—
Set eggs that did not hatch
—
Average expected females among actual hatchlings*
What this does NOT prove: A hatch percentage alone cannot establish how many eggs were fertile, why embryos did not survive, or whether the seller, transport or incubation caused the outcome. There is no scientifically valid universal “good/bad/ugly” grade for a single small shipped-egg hatch.
*A female/male estimate assumes roughly independent, equally likely sexes. Real broods fluctuate, and some genetically sex-linked crosses or species may require special interpretation. The calculator does not sex individual hatchlings.

2. Plan a future order
There is no guaranteed shipped-egg hatch percentage. Enter your own hypothetical hatch percentage to explore the mathematical possibilities—not a farm forecast.
This is YOUR scenario; no percentage is assumed for your purchase.
Why hatch results vary
Parent-flock fertility, egg age and handling, shipping conditions, incubator calibration, ventilation, turning and embryo development can all influence results. Candling shows development when it is visible; an egg that appears clear may not establish why it failed.
