Well, think of it this way:
Ants, they are a lot like Xenos in the way of behaviour and hive structure, Ants from different nests attack and kill each other, in order to make thier group the only one. (although I think i've read from somewhere about ants taking other group's ants as slaves)
It makes sense that Xenos -being much more agressive buggers- would kill each other, Thet way, only the strongest would survive.
EDIT:
A lot like Humans in a way: I mean we have wars against other countries, and Xeno hives would be like countries to them in a way, so mmaybe they have wars too!
