My quail are 4 weeks old. I'm looking at moving them out into the yard. I've got a rabbit hutch I was going to house them in. The rabbit hutch sets directly on the ground with no bottom for the "run" portion. Questions are: Do I have to raise the "run" off the ground? I'm going to have hardware cloth surrounding the whole thing buried a foot down. Plus I've put hardware cloth around the whole inside of the run so nothing can get it's hands inside. IF I can leave it on the ground, what would be best to put in the run? Sand, pea gravel or mulch? Any help would be greatly appreciated!!
