i see some easy to make models and will go with that.
I think that would more then likely be your best bet. I haven't seen anything small. The only thing I have seen, was for chickens and waterfowl, and if you used one of those on quail, I don’t think there would be any bird left.
When you finally come to terms on making one, post a picture for the others to see, it could be interesting, and beneficial to others.
