Fontaine didnt seem to have any use for any 'Little Brothers' as they didnt help him get more ADAM (was Little Sisters Orphanages not Little Childrens Orphanages), which should have raised some question in-game about why that might be (just one Audio Diary would have served) and what he might be upto (just like his murderous thuggery should have made him Public Enemy #1 almost immediately). But then, logic was not to get in the way of the Plot.

So real orphan 'boys' would be roaming the streets, hiding in dark corners, and perhaps some other people would make some orphanages, but wouldnt have the money to do what Fontaine did. So their psychological state would be about right forr making them feral, and combined with ADAM that would make for an interesting outcome.
