Set the hard limits
Existing coop and run dimensions cap flock size. If you are planning new housing, the calculator works in reverse and estimates the space the recommended flock needs.
How it works
One planner, three decisions solved together
Most chicken tools answer only one question. This one connects flock size, breed choice, and housing so a recommendation cannot quietly exceed your available space.
Match the birds
Breed traits are weighted by climate and your priorities. Missing evidence is discounted rather than silently treated as average.
Compare real alternatives
The best overall flock is followed by up to two genuinely different alternatives when they clear the quality threshold—not trivial reshuffles of the same birds.

The algorithm does not choose a breed because we can earn money from it.
Recommendation logic and monetization are deliberately separated. Affiliate availability, product price, hatchery relationships, and ad revenue are not inputs to breed or flock scoring. Source confidence is.
