Did you specifically buy unprocessed eggs? Most brine shrimp eggs that you buy from pet suppliers have already been decapsulated, so all you have to do is hatch them in a brine solution and then feed the baby shrimp to your fish.
((I'm not sure about the method since I've only hatched ones that came pre-processed))
