I would be worried about my cur dogs lineage if it had any retrieving instincts. But you could train them to locate the bird while on leash and take the bird from them real quick or before they get it.

I did not think about a leash. I know there only a few feathers left in the yard when one get caught so I would have to be right there. I may try a leash just to see if she will figure out to find them.
