Brine shrimp help
 

First of all I'm not sure if this is in the the correct category, but they're invertebrates :p

Okay so I'm just wondering what I need to hatch these guys,

I have a little container that I bought full of eggs,

I just need to know materials and steps to hatch them :) and also will they breed on there own? Is it difficult to breed them?

And just out of curiosity, how the heck do they get the eggs? Im just mind boggled :p

Also can normal table salt be used for them? Or seasalt?

Thanks for all help!
