Every egg, individually
Eggs are records, not a count. Each carries your own number and laid date, can sit in an incubator while staying its clutch's egg, and keeps its fertility, candling result and hatch outcome.

Dates that schedule themselves
Log the lay date. The rest follows.
Record the day an egg is laid and AviLedger schedules the candling window and expected hatch from that species' incubation period, egg by egg, then reminds you when each one comes due.
All features| Stage | Cockatiel | Budgerigar |
|---|---|---|
| Egg laid | Day 0 | Day 0 |
| First candling | Day 7 | Day 6 |
| Expected hatch | Day 19 | Day 18 |
| Ringing window | Day 8–12 | Day 6–9 |
| Weaned | Week 8–10 | Week 6–8 |
Incubation periods from the app's species catalogue. Ringing and weaning windows vary with the individual clutch.
Chick growth
Catch a chick falling behind, early.
Every weigh-in is charted and checked against the species weaning weight. A chick that loses weight or stops gaining is flagged, days before it becomes obvious in the nest.
Season summaries
Fertility and hatch rates per pair and per species, so next season's decisions rest on this season's results. The aviary's owner sets the month the season starts, once for everyone.
Chick to bird
Mark an egg hatched and the chick's record is offered there and then, with its parents taken from the pair that laid it, even if another pair raised it. Chicks still without a record wait on Home.
Start the season with the dates already in the diary.
