Amrock
Gallus gallus domesticus
✨ Fait Amusant
The Amrock essentially split from the Plymouth Rock gene pool over a century ago and has been bred in isolation by German fanciers ever since — making it one of the longest-running closed-flock chicken breeds in continental Europe. Genetically, it is now distinct from the American Plymouth Rock despite their shared ancestry.
A German-developed dual-purpose breed derived from the American Barred Plymouth Rock, standardised separately by the BDRG and recognised by the EE Europastandard as a distinct breed. The Amrock was developed from Plymouth Rock imports that arrived in Germany in the late 19th century, where German breeders selectively bred the barred variety into a heavier, more productive bird with slightly different conformation — broader, deeper-bodied, and with more tightly defined barring. The breed's name is a German portmanteau: 'Am' from American, 'Rock' from Plymouth Rock. Amrocks are exceptionally calm, reliable layers of brown eggs, and their barred plumage makes them one of the most recognisable farm breeds. Unlike the Plymouth Rock, which has multiple colour varieties, the Amrock standard focuses almost exclusively on the barred pattern. The breed is popular among German and Dutch smallholders for its uncomplicated, productive nature.
