Frozen Baby Brine Shrimp for Baby Discus?

[Klawz]

After doing some research it's said I should supplement two to three week old fry with newly hatched brine shrimp. Just wondering, even though obviously less then ideal, would frozen baby brine shrimp work? Not having brine cysts or any experience in hatching them plus this brood of babies getting to two day old wrigglers much to my surprise has caught me off guard. I also have Hikari first bites???

Any advice would be appreciated! Thanks
