If she isn't missing too many feathers, and doesn't look too worse for wear, it should be OK. But as soon as she starts to get too popular, to the point of her looking unhealthy, find some way of dealing with the extra roos. If it's an option available to you, I would purchase a few more hens, just to be safe, and, the more hens, the more eggs, right? Even just one or two hens would make a difference.
