If the shrimp were live they wouldn't need hatching.
Brine shrimp cysts are sold to hobbyists who wish to hatch and feed the newborn nauplii to their fish.
Hatching them is no problem; growing them out is labour intensive and fraught with problems.
While you can buy the ready made hatchers, most people just use a two litre pop bottle and cut the bottom out of it. Invert this in something to hold it upright, (the bottom of another bottle works fine) add salt water, aerate with a rigid air line tube extending down into the bottle cap, (now the bottom of the container) and add brine shrimp cysts.
Actually, it's better to add the cysts and let them soak for a couple of hours before putting the airline tube in. This way more stay in solution rather than be skimmed out of the water where they do no good.
If some get pushed up on the sides of the container, just swish the water around to get them in solution again.
The main problem people have in failed hatch outs is purchase of improperly stored cysts.
The cysts need to be refrigerated, but many stores just keep them on the shelf, and in time they become useless.
I buy mine from Brine Shrimp Direct, and never have a problem with hatching. Their price is also the best I've been able to find, especially for the quality of the ones I buy.
