HA–01
Eight rungs, four quizzes each
Breed Challenge lists every quiz at once, but only Chicken Breed Basics starts unlocked. Finish all four quizzes in a level — any score — and the next band opens: Recognizing Popular Breeds, Egg-Laying Characteristics, on through Advanced Breed Knowledge. Filter by Easy, Medium, or Hard, or by Breed Identification, Egg Production, Breed History, Physical Traits, Temperament, and Climate Adaptation. Each card keeps your best percent.
HA–02
A library that marks the last line
Search by title or filter All, Heritage Breeds, Egg-Laying Breeds, Meat Breeds, Ornamental Breeds, and Breed Characteristics. Cards show the tag, a one-line brief, and a reading time. Order follows the syllabus, from The Origins of Domestic Chickens to Choosing the Right Chicken Breed. No percent, no level credit — only a Read mark once you reach the end.
HA–03
Five eras on one vertical line
Step Early Domestication, Ancient and Medieval Breeds, Breed Development Era, Modern Poultry Breeding, and Contemporary Breed Conservation with side arrows or a jump to the first or last mark. Events stack oldest to newest: a date or approximate span, a title, and a short note — domestication, the spread across Asia, exhibitions, heritage conservation.
HA–04
Questions that explain the miss
A quiz shows “3 of 10,” the prompt, and three or four choices. Confirm, see whether you were right, read a short explanation, then continue. The result screen gives your percent, right versus wrong, and a retake. Those finishes are what fill the Hub bar.
HA–05
A Poultry Explorer card that stays put
The profile opens as Poultry Explorer until you rename it. Pick a favorite — Silkie, Leghorn, Orpington, Plymouth Rock, Rhode Island Red, or Sussex — and set a photo from the camera or library, or remove it. Counters show Current Level, Completed Quizzes, Best Quiz Score, and Articles Read. Clear History returns you to the first level and wipes quiz passes; your name, photo, favorite breed, and onboarding stay.
