A few helpful comments: Golden Comets and red sex links are supposed to be the same bird. In a mixed batch of "straight run" chicks (both sexes), the hens can be distinguished from the cocks by their coloration, they are a darker yellow-red and have what appear to be two dark "stripes" running down their back, whereas the cocks will be an overall light yellow bordering on white. This is intentional, they were bred this way to readily distinguish between the sexes at hatching. These birds are hybrids, meaning a cross between two distinct breeds (or pure lines), characterized by uniformity and heterosis, where the offspring out produce either parent. Those wishing to hatch out eggs should not use eggs from these hens, since you will get segregation of the genes in the F2 generation, which manifests itself in non-uniformity of type and lower productivity. In terms of their personality, they are wonderful birds, much less aggressive, flighty, and neurotic than black sex links, and do great as foragers when allowed to roam. Hope these comments are useful and add to someones knowledge!
