## What is Coop Calculator?

Coop Calculator tells you exactly how much space, feed, and water your chickens, ducks, quail, rabbits, and goats need — no login, no ads, no subscription.

Just pick your animal, enter how many you have, and see your results instantly:

• Coop and run space (indoor housing + outdoor run, with a separate figure if your flock gets daily free-range time)
• Roosting bar length and nest box count for chickens
• Daily feed and water needs, including a heat-weather warning
• Rabbit hutch space by breed weight class
• Goat shelter, pasture, hay, and water needs — including the exact water-per-milk-produced formula for dairy goats

EVERY NUMBER IS SOURCED
Every figure comes from university Cooperative Extension publications (Virginia Tech, NC State, Purdue, Penn State, and more) or the American Rabbit Breeders Association — not guesswork. Anywhere we couldn't find a confirmed source, the app tells you clearly instead of pretending to know.

YOUR WHOLE HOMESTEAD IN ONE PLACE
Save multiple flocks and see a combined homestead dashboard: total housing space, total pasture, and feed/water broken down by animal type — something no single-species calculator can do.

BUILT-IN REMINDERS
Set your chicks' current age and get a reminder around the usual 8-week (grower feed) and 18-week (layer feed) transition points.

SETUP CHECKLIST
Turn your results into a checklist you can check off as you actually build your coop, hutch, or shelter.

PRIVACY FIRST
No account, no login, no data collection. Everything stays on your device.

Free: calculate as much as you want, save 1 flock.
Pro (one-time purchase, no subscription): unlimited saved flocks, the homestead dashboard, and feed reminders.
