Because this taxon comprises more than 8,000 species, the choice of euthanasia method for a particular bird will depend greatly on its species, size, anatomic and physiologic characteristics, environment, degree of domestication, clinical state, and anticipated and actual response to restraint.
Birds differ anatomically and physiologically from mammals and these differences will affect whether and how particular euthanasia methods may be acceptably applied. Because birds lack a diaphragm, they have a single coelomic cavity, rather than separate thoracic and abdominal cavities.
Because there is no diaphragm, birds need to be able to move their sternum ventrally and cranially to breathe.261 Birds also have hollow, pneumatic bones, such as the humerus and femur, which communicate directly with the respiratory system.
A bird’s respiratory system has greater capacity to process air than a mammal’s due to a unique unidirectional flow of air through the lungs (which prevents mixing of inspired and expired air), more efficient gas exchange, and a greater surface area over which O2 can be exchanged (more and smaller air capillaries [3 μm] than the smallest mammalian alveoli [35 μm]).261 Because of their greater capacity to process air, birds are more sensitive than mammals to inspired toxicants (eg, the proverbial canary in the coal mine collapsing before humans detect the methane in the air).
Nitrogen and argon—Administration of N2 or Ar is ONLY acceptable in anesthetized mammals! as a coexisting O2 concentration of < 2% is necessary to achieve unconsciousness and death.

Achieving that condition is difficult. In addition, Ar has been shown to be highly aversive to rats. Although N2 and Ar can kill animals,82-84 other methods of euthanasia are preferable.
So if N2 is ok or not for humans still need to be tested, but one thing is sure, the way they applied the death execution was just shit 💩!
