I had some that were opened and 10 years old and they hatched. I think if they are kept dry, they will hatch, the count might be lower.

what was the temp and what kind/ how much salt did you use?

what kind ? tbsp into how much water?
If some hatched under you current conditions, you might have hope that you can find conditions to get more to hatch. You need about a tablespoon of marine salt per pint of water. Marine salt has a buffer that keeps the pH up around 8, if you use plain salt, add baking soda or baking powder to get the pH to 8. At 70 degrees it takes about 48 hours. At 80 F it takes about 24 hours to hatch.
Dry eggs that have not been subjected to high temperature for very long will last for ever, well maybe not that long. Eggs that get wet don't last long.
If they do not hatch or very few hatch, you can decapsulate them in Clorox to remove the outer shell. Fish readily eat the resulting eggs, but they are not so great for new fry since new fry need something moving to get more motivated. PM me or Bob Bock for the procedure, although many other probably have the procedure.

Whfenever I buy a can and open it I always keep them in the freezer. So far it works.

How I Hatch brine
I hatch a batch every day.
Quart Mason Jar, drill 1 hole in the middle, for the ridgid tube(tight fit) and 2 smaller holes for the air to escape.
Ridgid Air tube
flex air tube
air pump
40 watt bulb in round clip reflector from hardware store
This has worked for me for the last 6 months
Another note: when the lid and screw cap get rusty, replace as the rust may contaminate the water.

- fill declorinated water to top line of mason jar
- add 2 tablespoons of marine salt (tried table salt + baking soda but didn't work as well)
- 1/4 teaspoon of eggs
- put the light bulb about 4-6" away from the jar
- 18Hrs you have a hatch
- after they hatch I move the jar away from the light, the brine shrimp last longer
