You are the only one who can decide whether or not to move her. Is she safe from predators where she is? Is she in the coop with the flock? If she's safe, and you're comfortable leaving her with the flock, you could leave her. I would mark the eggs, though, that she's been sitting on and check under her daily to remove any extras that may have appeared (sometimes another hen will get in the nest to lay an egg while the broody is taking her daily break). Many people just let the hens hatch within the flock, and don't have any problems. The broody is very protective the first few weeks, and when they're raised in the flock from day one, integration is not a problem. When they're separated for a period of time, integration can be a little trickier. Mom isn't as protective, and the other hens are more likely to give the young ones a rough time. If you should decide to move her, it works very well to do it at night. It seems to be less traumatic for the hen to wake up in a new place than to be moved during the day and getting all upset. In my setup, I can divide my coop into two pens. I like to separate them while they're setting, just to keep the other hens out of the nest. I kept them separate for a week or two, then let them mix with the flock. Mom was still protective enough to keep the other hens from being a problem. The reason I kept them separate is because I free range and have some wild barn cats that live in the barn near my coops. I figured the babies stood more of a chance of escaping harm when they were just a bit older. When I integrated the hens and chicks, there was no problem with the other hens pecking the babies or picking fights.
