Nice system...fairly self-contained and limited human contact gives them the opportunity to act more 'wild'.  Price is pretty steep though.  From what I'm told the key to quail management is predator control and habitat...if you have those 2 nailed down then this system is icing on tha cake. 

I've been itching to try this but can't bite the bullet and spend that much money.  If I could get some positive feedback from folks that had used it, I think I could get my neighbor on board and we could split one.
