Armadillos eat grubs, worms and insects. With terrible eyesight they rely on using their sense of smell to hunt and those ears won't just be radiators. So, spread a load of foodstuffs in a relatively confined area, stand downwind from them and whilst they're feasting, snap away. Hopefully, shots of them feeding will suffice.

Leprosy's curable these days, btw. You just need to get diagnosed early. Good luck with the photos.
