Are Golden Buffs and Golden Comets the same bird? If not, what are the differences?
Golden Buff vs. Golden Comet

They are both sexlinks (hybrid layers). I'm not sure of the cross that makes the Golden Buff, if it's any different, but they are essentially the same type bird.
Red Sex-Links are the result of various crosses. White Rocks with the silver factor (the dominant white gene would produce all white offspring) are crossed with a New Hampshire male to produce the Golden Comet. Silver Laced Wyandotte crossed with New Hampshire gives the Cinnamon Queen. Two other crosses are obtained with Rhode Island White x Rhode Island Red, and Delaware x Production Red. These two crosses are simply called Red Sex-Links. Males hatch out white and, depending on the cross, feather out to pure white or with some black feathering. Females hatch out buff or red also depending on cross, and they feather out in one of three ways.
1. Buff with white or tinted undercolor (such as Golden Comet, Rhode Island Red x Rhode Island White)
2. Red with White or tinted undercolor (Cinnamon Queen)
3. Red with Red undercolor (Delaware x Production Red) (In this color pattern it is almost impossible to distinguish daughters' color from father's color.)
Meyer calls theirs Golden Buff. Here is the link:
