My advise is stay away from pen-reared birds! Pen-reared (or preserve) birds only complicate matters by teaching the dog to do what it shouldn' t -- catch birds. If this is your only option, lose the quail and only train with roosters (pheasant), which are less likely to be caught. Also, if you know of an area that holds woodcock, run your dog on them, since they should be back in your area by now.
