Answer: There is an image of Sempervivum tectorum or hens and chicks at the following web page. You may need to cut and paste the complete url into your browser to make it work correctly.
There are several different varieties of this plant so yours might not look exactly the same as this one.
If the bed is full of weeds you may not be able to weed it without first lifting the Sempervivum. It transplants easily, especially the smaller ones, so you will not be killing them if you do it.
Loosen the soil, then set the plant on the surface. Wiggle it a little to get good soil contact but do not bury it or try to plant it deep into the soil. The roots will find their own way downward. This is a good time to move them or replant them. Enjoy!
