they need live food to thrive, i have not heard of a non-aquatic frog living on flake food or frozen food.

you should order in bulk if you have that many toads, southerncricket.com is a good place to get them from, you can order in quantities of 500 which should last you a while

i'm not sure how large the froglets are, but you could also try culturing fruit flies, email me at mynameisMnM@gmail.com if you have any questions about culturing them.
