I remembered a few months back I watched taiwanese variety show "Guess 3" that covered on the topic of a taiwanese lady breeder. She mentioned that she separate the bigger size shrimps from the pool of shrimps so as to aviod the smaller size shrimps from eaten up. So conclusion from her is that the shrimplets may be eaten up by larger shrimps. But for me I just leave it as it is in the same tank.
I think it is inevitable to experience small shrimplets death due to initial stage of molting.
