Hatch. Breed. Collect.
A discovery game for real chicken breeds. Explore stylized worlds, hatch 250+ heritage breeds, and breed for rare egg colors with genetics modeled on the real thing — all while keeping your actual flock alongside your virtual one.
Start your coopA whole basket of color
From porcelain white through dark chocolate, the blue-gene line into sage, moss and deep olive, and — for the dedicated breeder — five mythic shells hidden behind a recessive gene. Every color here is one you can chase, breed toward, and lay in your own coop.
Mythic shells
Discover
Explore six themed worlds to find eggs and catch rare breeds, and claim a free hatch from your daily nest.
Incubate
Eggs hatch over real time. Reveal the breed partway through, then hatch it into your growing flock.
Breed for color
Pair a hen and rooster and watch real Punnett-square genetics forecast the egg color of their chicks before they ever lay.
Six real loci
Blue, brown, lavender, sex-linked barring, the E-locus base series, and the recessive exotic shell all inherit the way they do in real birds.
Master the Codex
Catalog every breed you hatch, learn why each chick turned out the color it did, and chase the rare crosses with the Breeder's Almanac.
Your real flock too
Keep your actual backyard chickens alongside your virtual ones — Henbrook Hollow is built for keepers, not just collectors.
