The alternating hard/runny stools indicates a digestive track problem (either not digesting properly or getting constipated and then finally able to go). I think probiotics are the way to go for sure.
I'd do the same as above..just start fresh with probiotics and chicken and rice.
Gradually add back a puppy kibble (maybe chicken based instead of duck). I might even give a tiny bit (maybe a tablespoon) of canned pumpkin with the kibble if runny stools start up again.
Has she been tested again to make sure all infection is gone?
