AviLedger — Bird Breeding

AviLedger is record-keeping software for bird breeders. Keep your whole aviary — every bird, pair, clutch and chick — in one place, on your phone in the birdroom and on your desktop when you sit down to plan.

Works offline. Your records are on the device, so the app opens and keeps working with no signal. Anything you add is saved and syncs automatically when you're back in range.

YOUR FLOCK
• Full bird profiles: species, ring/band number, sex, mutation, parentage, status, value and photos
• Rows and cages that match how your aviary is actually laid out
• Import your existing flock from a spreadsheet — no retyping years of history

BREEDING
• Pair your cocks and hens and track every round
• Visual egg board: laid, candling, fertile, infertile, hatched
• Candling and hatch dates scheduled automatically from each species' incubation period
• Turn a hatched egg into a chick record in one tap

GENETICS
• Mutation and split inheritance, autosomal and sex-linked
• Pairing predictions — see the expected outcomes before you commit to a pairing
• Pedigrees and inbreeding coefficients (COI)

CHICK GROWTH
• Weigh-ins plotted against the species weaning curve
• Early warning when a chick falls behind

COMPLIANCE & PAPERWORK

Recent changes:
Number each egg with your own number and laid date, and trace it to the chick. Add incubators and move eggs into them. Marking an egg hatched offers to create the chick's record. Sort the Birds list by ring, age, species, cage or recently added. Starred species come first in the picker. Suggest a missing species or mutation, or add your own. More budgie mutations, and greywing and dilute combine correctly. Export to a spreadsheet from More or the Birds list.
