The ones coming from Sunnyside are going to be hybrid, so if you do hatch those eggs there really is no knowing what the chicks will be like - they could end up scrawny without much meat or even not lay very well. They will probably not be sex-linked either. But they are sold as a dual purpose, supposedly they are slower growing than a broiler, get to a good size with good meat and will still lay decently for eating eggs.
The "S" breed is called Sagitta. I have 9 of them in my brooder right now. I can identify the 3 blacks that I ordered, but cannot tell the difference between the 3 Browns and the 9 Sagittas. They are growing fast so hopefully I can sort them out when they grow up. If not, no big deal as they are just for eggs and eating.
If you have some purebreds and like the breeds you have - then pen up a breed and eat the eggs for a week. Then save the eggs for hatching and when you have enough let them out into the flock again. There may be a little bit of tussling when they go back into the flock until they establish their pecking order once again.
