It depends. A given hen of some breeds will never go broody. Others like my American Dominiques might lay 180 in their first season of lay without going broody and lay another 100 in second season before they do go broody. My American Games can go broody after laying only a few eggs when older and can produce almost two dozen as a pullet just coming into lay before going broody. Those games that have already produced a clutch of eggs very reliably produce a clutch of 10 to 12 eggs before going broody. Genetics and age clearly important by limiting nutrition can make for smaller clutches at onset of broodiness.
I hope that helps.
