I use my LG for everything, and it works pretty good. I have only hatched quail twice, technically, but they were two different breeds that were going at the same time. I had a horrible hatch, but I didn't know what I was doing with them either. I have more buttons in a borrowed LG, and more A&M's in my LG. The A&M's don't seem to be doing anything at all, but 2 are dark so they are staying. I won't know about the buttons for 2 weeks, so we'll see how they do. I have heard that quail need a bit lower temps, and higher humidity, so that's what I'm doing with the buttons. Hope it works out!
Another thing I've heard is that shipped quail eggs are hard to hatch. Maybe you can hatch eggs from your own, or get some more adult birds to get a better start.
