Pet stores here charge 39 cents apiece for those! Lucky I can scoop them out of the ditch for free
Make a close observation of the shrimp before moving her. The eggs will appear some time before they are fertilized. Initially they are carried inside the shell, then the shrimp mates immediately after molting and the eggs are externalized and carried in the swimerettes in the tail (same place they were before, but slightly further down, so look closely - you'll be able to see her fanning them to get water movement at this stage).
The larvae are quite small and probably would get eaten by fish fry of any sort, but it's worth a try. They also are not strong swimmers, so filtration may be a problem for them. I've had limited success using just a bucket with no filtration. The single shrimp doesn't produce enough waste to require cycling, and they're happy enough to eat algae and various infusoria if you just put some bits of plants in there with them.
Some species of ghost shrimp require brackish water to breed, so you may not be successful in any case, but some will be fine in fresh water. I don't know how to tell the difference between the two except by collection location.
