Well getting involved in the process wasn't the best thing to do imo.
Theres a bigger problem here and that is the social hierarchy with the other hens now needs to be reestablished. So unless the broody and chicks are completely separated from the flock the broody has 2 challenges - protect her chicks and protect herself from other hens. In this scenario the chicks will come out with the worse of it.
If it were me I'd put the hen back into the flock and the chicks in a brooder. Next time leave her in with the flock and she will take care of it. That's what's nice about a broody.
