Awesome! I love quail, and we'll eventually raise them here as well.
I used to have a friend in the 70s who inherited some land in the hills above Malibu from his parents.
After he got back from Vietnam, he wanted to do something seriously peaceful, so since hunters had pretty much obliterated the California quail in the Santa Monica Mountains, he started raising them to release.
By the time I met him, he had already released several hundred, and since he had his land fenced against large predators, the quail knew it was a safe haven, so a large percentage stuck around close to home, and kept on breeding.
I lost contact with him when I left California, but I've heard from several people that the California quail have made quite a comeback in the area, and I have no doubt that he was largely responsible. ;-)
Never doubt that one person can make a difference.
