  1. The killing of a sibling, especially as observed among certain species of animals. countable,uncountable

To me, the data clearly indicate a simple response to food availability, with the oldest young passively out-competing its smaller sibling for a limited resource. I still have not seen data to support "siblicide" as a strategy.
