Poppy sits with your birds one at a time. A photo, a name, a note on her comb — and the small changes across weeks stay easy to see. What you get: • A card for every hen — photo, name, breed, hatch-date, temperament • Comb, weight, and moult notes carried across seasons so patterns show up • Egg records kept per hen, not just per coop • Health entries in plain language, with vet-worthy signs marked plainly • Feed, treat, and dust-bath logs stored beside each bird • A coop-level view for run cleaning, bedding changes, and predator checks • Lookback pages that gather a hen's year on one screen How it feels: Poppy talks the way a patient keeper would. She names the hen before advising, keeps the pace unhurried, and treats the comb in morning light as the reading it is. No alarms, no urgency for its own sake — just a warm witness who's been round the run a few thousand times. Who it's for: • Backyard keepers with three to twenty birds who want to remember each one • First-year keepers learning what a healthy comb, crop, and moult look like • Long-time keepers who'd rather write once than remember everything Privacy: Your hen photos and notes stay on your device by default. Nothing about your birds is shared or sold. Full privacy policy is linked from settings. Poppy's ready when you are — one hen at a time.
