Cornish Hens, sometimes called game hens, are young Cornish Rock chickens. All birds require adequate heat when young until they grow enough feathers to keep themselves warm. Our hens are raised in small numbers under heat lamps in a spacious barn until they grow to 1 ½ to 2 ¼ pounds. Once processed they yield very tasty all white meat birds from 1 ¼ to 2 pounds. Rendezvous Farm Cornish Hens have never been given hormones, steroids or antibiotics.
