This is a fowl physician. It was born of a play on words during an annual physical. It’s obvious fowl need their own physician. They have to have check-ups. They need someplace to go when they have boo-boos or to get the occasional bit of buckshot removed.
“The Ductor…” has a stethoscope and a little white jacket-with no armholes, because fowl don’t have arms-and he wears a head mirror, the real name is a Von Schtupper mirror. How appropriate!
