Low brine shrimp hatch rate?

Question

I got a hatchery from the petstore, and it came with packets of pre-mixed brine shimp eggs and salt. I ordered some good eggs but these eggs from the pre-mixed packets have a really crappy hatch rate; probably less than 50%. Is there a way I can separate the eggs from the brine shrimp so I don't put all those eggs into my tank?
