Here is what Welp hatchery says about Comets.
"Red Sex Links are a breed cross using Rhode Island Red males and Delaware females. The females are primarily red while the males are primarily white; therefore, the sexes can be separated immediately following hatching. This layer is used in many commercial layer operations. They have excellent livability, and are very efficient producers of large brown eggs. Mature hens will weigh about 5 1/2 lbs. and can be salvaged for fowl meat when their use for laying is over. Mature males will weigh approximately 8 lbs
Red Sex-linked Chicken - Baby: can be color-sexed. Females are salmon-red color; Male are white. Mature: Red feather bird with some white showing in the tail, neck and breast areas. They are quiet and easy to handle, noted for her beautiful color and small body size, and an excellent layer of medium brown colored egg.
They are also known as Golden Comet, Gold Star, and Cinnamon Queen.
Weight: 4.5 lbs. (Welp)
