I'm not surprised that they don't use the house or ramp. Quail are ground birds, and while some can and will use ramps, it is a bit out of their comfort zone. Don't expect them to use the nesting boxes to lay in either.
If you haven't already, you may want to put some boxes or other places they can hide down in the lower area of their pen since that is where they will spend most of their time.
