Maybe there is some more Natural Selection happening.  It could be that the "strongest" chick is the first one able to break out of the shell and also is "stronger" in grabbing food from the parent and therefore grows biggest quickly and is able to kill off the weaker ones, thus preserving the "strongest" genes.


Is it possible also that the parent does some selection in choosing which gaping mouth to put the most food in?  It's an interesting question.
