Domestic chickens descend from the Southeast Asian red junglefowl, kept for over 3,000 years first for cockfighting and ritual, later for eggs and meat.
Victorian 'hen fever' in the 1800s produced most of the heritage breeds sold today, and the American Poultry Association's Standard of Perfection still defines them.
Care & housing
Allow 4 sq ft of coop and 8-10 sq ft of run per standard bird, with 8-12 inches of roost space each.
Feed 18-20% starter to 8 weeks, grower to point of lay, then 16% layer with free-choice oyster shell and grit.
Ventilate high and draft-free, keep bedding dry, and worm and check for mites seasonally.
Breeding tips
Breed from birds 9 months or older that show breed type, vigor, and good laying — not just color.
One cockerel to 8-12 hens; pen breeding groups two to three weeks before collecting eggs.
Toe-punch or leg-band each hatch so you can track which pairings produce your best stock.
