EmTy,
I have found one brand that is soy-free that will work for young quail (28% protein). It is H & H Soy Free Non GMO Gamebird. I'm not sure what percent of protein the older quail need, but this would work. I have also attempted to contact Jack, so we shall see what happens. I did check the soy-free forum on this site, but it was mostly for chicken feed. Of course the downside with that peanut butter feed is I'm also allergic to peanut butter. I will check this other and possibly add treats such as mealy worms to make it a tad more interesting. I have heard that some birds don't like this feed, but I suspect if they are raised on it, it should work.
Thank You,
Sue
