Answer:It is to ensure that a good percentage of offspring survive 
Explanation: As with most organisms, there is a good chance that not all offspring will survive, due to factors such as limited resources, predation, etc. Thus certain measures have to be put into place by the parents to ensure a good chance at survival for their offspring. In this case, the eggs that are widely spread out are seen as sacrificial ones, because the parents will not be able to fully care for them and provide resources for them and the ones which were laid in the nest. They will also act as offerings for any predator on thee hunt. All of this will greatly increase the chance of survival for the eggs which were laid in the nest and will receive parental care .
