You can leave her eggs there and she may come to them. In my experience, a hen has to become comfortable with her new home. I guess in her "henny" little way she wants to be sure she is safe and that her little eggy babies will be safe also. But for sure, we cannot make a hen broody. I can tell you, if we could, I would have a hen house full of broody hens right now. But no go. Not a one. Oh well, I have my incubator ....
