"To prevent this, Astalos guard their nest up until the eggs are ready to hatch before leaving the young to fend for themselves."

This implies that Astaloses try not to eat young from their own nest. If they come across other juveniles, then those are fair game (plus they're eliminating competition for their own young). Odds are, if there's an Astalos cannibalizing infant Astaloses, it's probably not the mother or father. Just thought I'd throw that out there.
