Aw so many house quail :D
I agree with Robecki, sand is great :) I used a mixture of sand and shell grit for a long time. The pine shavings isn't ideal because they eat it and it can clog them up a bit.
They don't really nest like flying birds, but will lay in a soft comfy spot if they can. Must admit mine just lay them willy nilly.
They're social critters, so do give her attention and love :)
