Coop Count

Tap who laid each morning. Coop Count keeps a quiet little book of your backyard flock, then shows you the rhythm of the coop and who is pulling their weight.

Built because a clipboard by the coop door keeps getting rained on. So I made the egg book that lives in your pocket.

What it does

A morning ritual, a season of data

One small app, three honest jobs: log the morning, read the rhythm, and know your hens.

Part 01

Log the morning

Walk the coop, tap each hen who laid, and add any eggs you found but cannot pin to a hen. The daily total adds itself up as you go.

  • One tap per hen, the way a real morning works
  • An "unattributed" bucket for mystery eggs, so totals stay honest
  • Pick any date and backfill the day you forgot

Part 02

Read the rhythm

A gentle chart of eggs over time, a rolling total for the season, and a plain-spoken ranking of who is reliable and who is taking it easy.

  • Laying-over-time chart that smooths the daily ups and downs
  • Consistency per hen, measured from the day she joined the flock
  • Optional "Ask the coop" read written by Claude from your own numbers

Part 03

Know your flock

Give each hen a name, a breed, and an egg color. Add a photo, or pick one of the painted breed portraits if she will not hold still for a picture.

  • Photo or hand-drawn illustration for every hen
  • Egg color on file, so the basket finally makes sense
  • Notes for the broody one, the bossy one, the favorite

How it works

From empty coop to season chart in three steps

No account, no app store, no spreadsheet. Add it to your home screen and it opens like a native app.

1

Add your hens

Name, breed, egg color, and a photo or a painted portrait. It takes a minute per bird.

2

Tap who laid

Each morning, walk the coop and tap. Add any mystery eggs to the unattributed count.

3

Watch the rhythm

Over the weeks, the chart fills in and the flock sorts itself into reliable and slacking.

Ask the coop

An optional touch: paste your own Anthropic API key in Settings and Coop Count will hand your laying numbers to Claude for a warm, plain-English read on the flock. The key lives only on your phone, so the public link is safe to share and every visitor brings their own.

Under the hood

One file. No backend. No tracking.

Coop Count is a single HTML file you save to your home screen. Every hen, photo, and egg log lives in your phone's local storage, and nothing is ever uploaded.

Single-file build Vanilla JavaScript localStorage PWA / home screen Optional Claude API Netlify No database

The data model is one tidy JSON object: your hens, and a record per hen per day. Photos are shrunk to small avatars before they are saved, so a season of logging stays light. There is no server, so there is nothing to breach and nothing to spam. The optional AI key sits in a settings panel on each person's phone, which keeps the link shareable and gives every user their own quota. A small app, built the way I think small apps should be built: useful first, charming second, and honest about where your data lives.

Try it

Go count some eggs

Open Coop Count, add your flock, and start tapping who laid. By next month you will know exactly who is earning their feed.
