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.
