I never seem to have any success hatching brine shrimp :-(
Can I feed the unhatched eggs to my fish after rinsing in fresh water?

NO! That's dangerous because they cannot digest the shells. It might
possibly be okay if they're decapsulated brine shrimp eggs (where the
shell has been removed), but I've never tried that.
I've hatched brine shrimp myself, and I can tell you that just hatching
them is easy if you just follow a few steps. Growing them into adults,
though, is considerably tougher and is a hobby in and of itself. It's
best to use a hydrometer so you can precisely measure the concentration
of salt - 1.020-1.030 is fine. A medical urinometer is the best kind of
hydrometer for this, in my opinion, because it's nice and small. If you
don't have one you can use 4-8 tablespoons of marine or kosher salt per
gallon of dechlorinated water, but I really don't believe in measuring
the salt by volume due to differences in size when it comes to salt
granules. You might also want to add a pinch of baking soda to get the
PH up to about 8.0, although this isn't strictly necessary it seems to
make the shrimp healthier. And you must use an air pump with an airstone
to provide strong aeration for them.

OK, I'll have another go, thanks.
If they successfully hatch, how then do you separate them from the shells?

The broken shells float to the top of the water and form a scummy mass,
and the unhatched eggs tend to stay on the very bottom. You can skim the
stuff off the top with a fine-mesh net, and use a turkey baster to
carefully remove the nauplii without sucking up unhatched eggs. One
trick you can use is the fact that brine shrimp like to swim towards
light. Just get a penlight, shine it in one spot for a while and they
will concentrate in that area.
