i use a container which is around 25 cm high, round cheap one , i popped holes in the top , and none seem to get out. even when i'm picking through them for the smallest ones they cant climb the sides, some try jump but they cant seem to make the leap. i put a egg carter in it also.

i only feed my frogs in a container with holes in it,also , only cause i read that crickets can hurt your frogs in set free in their enclosure, im not sure if this is true but i did not want to take any chances.
but at the same time, i have to disturbed my babies every evening to offer them food. which i do not like also,
id lvoe to know how others go about feeding time, and if crickets do in fact hurt lil frogs.
