Red sex links are produced by breeding a red rooster over a silver hen. The female chicks hatch out red or gold-based, the males are silver based. Thus the color is linked to the sex. Different breeds can be used for this cross and different hatcheries call their crosses different things....gold comets, red stars, cinnamon queens are the common names. They're usually great layers of large brown eggs, fairly docile and overall great family birds. Some folks here have had problems with health issues from being bred for high production, but that's a YMMV thing. Mine have been great.
