No comment needed  from  James Taranto,  WSJ:  Turkeys, pigs and even roosters have flown the friendly skies, carried onto commercial planes by passengers who identified the critters as emotional support animals.
But a committee of airline representatives and disabled rights advocates has been meeting for months in Washington, D.C., to come up with new rules on what type of animals should be permitted on planes and what documents are required to prove the animals are needed. . . .
The National Multiple Sclerosis Society, among others, suggests limiting emotional support animals to dogs, cats and rabbits, while other organizations, including the Autistic Self Advocacy Network, would like to add birds to that list (but not chickens, ducks or turkeys).
Some advocacy groups say passengers shouldn’t be required to carry a letter from a mental health professional confirming the need for an animal because it would be stigmatizing.
So let’s see if we have this straight: Carrying a letter is stigmatizing.
Carrying a duck isn’t stigmatizing.
