Actually commercial breeds have been carefully selected away from broodiness because a broody hen is not a laying hen and therefore not a productive hen (for eggs).
That is why you rarely get a broody Production Red or White Leghorn or RSL or BR...the industry has been selecting for prolific laying which deselects for broodiness.
It takes the right genetics to create the proper hormone balance for a hen to actually settle into a deep brood that will sit for 24 hours for 21 days to hatch chicks....then mother those chicks.
This is different than dominant nest behavior which is simply insisting the nest is yours when you want it, and you want it whenever anyone shows interest....but not sitting in a deep trance round the clock. Many brooding hens barely notice others, many scream in hostile anger if anyone comes near their nest. But all brooding hens will sit 24/7 for 3 weeks getting up once a day or even once every several days to quickly eat/drink and leave one monumental and stinky poo to immediately go back to the nest to incubate those eggs.
To have the genetics for that, you typically have to look at the "heritage" breeds or game breeds or the orientals like Silkies and Cochins.
But occasionally, the genetics are passed down to a commercial breed hen, and yes, she can go broody...but as I've stated previously, in my experience they do not have the sticking power but sulk more than produce a productive brood that will hatch chicks.
