Yes, that is a male bobwhite. I would not mix quail with any other poultry, especially chickens as they can carry diseases that can kill quail. Also, birds you just received from a swap can carry diseases as well.
He's a very pretty quail. I'd love to have a bobwhite myself, but found out I'd need to pay $50 a year for a game bird license to be able to have one. So button and coturnix for me!
BTW, when you say you got him at a swap, does that mean you traded something for him or just paid for him? I've been to reptile shows and have bought reptiles much cheaper there than anywhere else. Is it the same for a poultry swap?
