Should I track individual birds or just the flock?

Support both, and let the keeper choose per flock. Six hens with names are individuals and their keeper wants per-bird health notes; forty birds are a group and per-bird tracking would be abandoned in a week. Forcing either model onto the other is the fastest way to lose half your users.

Why does egg withdrawal after treatment matter?

Because some poultry medications leave residues in eggs for a period after dosing, and the whole point of keeping chickens for most people is eating the eggs. Recording a treatment without surfacing the date the eggs are usable again is worse than not recording it at all, so make that date a visible state on the Today screen, not a note buried in a history list.

How to Build a Backyard Chicken App with AI (2026)

What a backyard chicken log app needs

Daily egg count logged in one tap from the home screen
Flock records per bird or per group: breed, hatch date, status
Feed and bedding purchases with running cost
Cost per dozen, laying rate, and seasonal production chart
Health and treatment notes with withdrawal-period reminders

The screens

Screen	What it does
Today	One-tap egg count, feed level reminder, anything due
Flock	Birds or groups with breed, age, and status
Production	Chart by week and month, laying rate, best and worst spells
Costs	Feed and supply purchases, cost per dozen, cost per bird
Health	Notes and treatments per bird with withdrawal dates

The data model

Flock: name, startedOn, coopNotes
Bird: flockId, nameOrTag, breed, hatchDate, sex, status, exitedOn, exitReason
EggLog: flockId, date, count, crackedCount, notes
Purchase: flockId, date, category, description, amount, quantityKg
HealthEvent: birdId, date, kind, description, treatment, withdrawalUntil

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

“A backyard chicken keeping app. The home screen is Today and its job is one tap: log this morning’s egg count. Default the number to yesterday’s count so the common case is tap-and-confirm, and allow a separate cracked count because people want the real laying rate, not the usable-egg rate. Flock holds the birds, either individually with a name or leg-tag when the keeper cares about individuals, or as a group count when they do not — support both, because a keeper with six named hens and a keeper with forty birds are the same customer at different scales. Each bird records breed, hatch date, sex, and status, and when a bird leaves the flock the app records when and why rather than deleting it, so historical laying rates stay correct. Purchases log feed, bedding, and supplies with an amount and, for feed, a weight. Production charts eggs by week and month and shows the laying rate as eggs per bird per day, which is the number keepers compare with each other. Costs is the screen that earns the app: total spend, cost per dozen, and cost per bird, presented plainly even when the answer is unflattering. Health records notes and treatments per bird, and any treatment with an egg or meat withdrawal period sets a clear date after which eggs are usable again — that reminder is a genuine safety feature, so make it prominent rather than a footnote. Works offline; coops do not have wifi. Screens: Today, Flock, Production, Costs, Health.”

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

A one-off unlock around $5–10, or a very cheap annual tier for charts and multi-flock support. This is a hobby audience with free spreadsheet habits and little tolerance for a subscription on a chicken app, so keep daily logging free forever and charge for the analysis and export. Realistically this is a small-revenue, low-support app — a good first build and a bad business plan on its own.
