Original AviLoft guidance · Updated 24 October 2026 · General information, not veterinary advice.
Check both parents’ ring numbers and available ancestry before pairing. Record the pair and nest box so eggs and youngsters remain traceable.
Note laying, the observed start of incubation and actual hatching separately. Around 18 days of incubation is a reference point; the calculator is a reminder, not proof of an event.
Keep foster-parent care separate from biological parentage. Record changes when they happen rather than reconstructing them at the end of the season.
Background references, not an endorsement of AviLoft. Estimated dates and general guidance do not replace observations, official rules or professional advice.
