I used to raise and train Springers, and used Pigeons for the training. Easy to keep, easy to catch, easy even to raise if your so inclined.
I did raise pheasant and quail. gave up on the quail, not enough meat on them, but the pheasant were no issue at all. Bought Viable eggs every year and hatched them in an incubator. Chicken wire enclosure worked quite well.. I had less than 300 dollars in the whole pen... of course.. that was... 20 years ago... or more... BUT, there is enough meat on a pheasant to make them worth eating!
