According to the size you should be feeding your frogs, they don't make no noise whatsoever! Crickets usually don't make a peep until they are adults size. I have a experiment going on at home too... I order between 3/8 to 1/2 crickets.. I kept one of the last 1/2 as a pet cricket as I want him to grow adult size to start chirping! Lol I miss the country and that would be my only escape.. Cricket chirping! Lol

But don't worry, youll be just fine
