I have a farm. From my barn, last year I ran 12-3 UG conducter out to my pasture to an outlet for the water tank heater. This year my plans are to put a run in shed for the horses. Right now I have one lead and nuetral on a GFCI breaker. Can I use the other conducter on a seperate circuit using the same nuetral conducter? Both of them will be GFCI since its an outdoor structure and I dont want my horses to become fried critters. Also is it possible to put a fence charger on a GFCI circuit without it tripping?

No, you can't share a neutral if you're coming off of a single pole GFI. Put the GFI protection at the end of each hot circuit & your multiwire circuit will work. Or, if you like spending money, but a 2 pole GFI breaker.
I have a fence charger plugged into a GFI & it hasn't been much of a problem. Trouble is, you have to keep checking it to make sure it hasn't tripped, unless , of course, you have your horses trained to come to the house if they get out of the pasture.
