Does egg size make a difference when hatching chicks?

[JMarch]

Wondering if anyone selects only the biggest eggs for incubation and if it affects anything like chick size, chick health, larger size in adulthood?

it doesn't change the chick but can make it harder to hatch if its a smaller egg so bigger eggs are best make sure its not a double yolker though they tend to not hatch
