Ella, how's the other one from me doing? Is he/she eating for you? Strange turnabout with them.

Regarding medicating the others, they should be treated with fenbendazole (Panacur) and metronidazole (Flagyl). Panacur should be used once a week for 2-3 weeks. Flagyl only requires 1-2 doses, say once each week half way through the first 2 weeks (between the Panacur dosages). You _can_ administer these medications yourself, provided your state laws do not prohibit acquiring them. Some forms of both medications are restricted to prescription only but you can acquire them in other forms (i.e. there is flagyl sold for fish that is not prescription only - you can buy it through amazon.com). Large animal supply stores (like Valley Vet) are useful too. The easiest method is to acquire them as powder (or tablets that can be powdered) and dust food items with the dosage and make sure each frog eats the dosed food items.

For amphibians, the dosing for Panacur is 50 mg/kg (for every kg of animal weight, administer 50 mg, so for an animal that way 100 g, you want to give it 5 mg).

In the case of Flagyl, the dose for amphibians is 50 mg/kg too. Bruce Maclean ("Herpvet") suggests using probiotics instead of flagyl unless there's a serious problem that indicates flagyl. This is a quote of Bruce in Caudata.org regarding probiotics:

Theory is that they are beneficial, or at least neutral, microorganisms that compete with (hopefully out-compete) potentially harmful gut microorganisms (see http://en.wikipedia.org/wiki/Probiotics for more detail in humans).
