You're right. The first to hatch is the first egg laid and will not necessarily be the offspring with the most 'fit' set of genes for the environment. The evolutionary implications of chick aggression is not so much selection for the strongest chick, but a battle for each chick to dominate the inherently limited supply of parental investment.
