If I understand correctly, if someone wants to keep an extra-super-high standard of kashrut for themselves, s/he can look for "chalak beit yosef" beef, which means ("super-glatt") the lungs had virtually no adhesions on them.
With poultry, my understanding is there's no such thing as "glatt"; if the chicken's organs look okay it's okay; if there's any questions, it's no good. Hence no such thing as "glatt" chicken.
Are there other issues where some higher standard of kashrut with regards to poultry comes up? Can I buy "super-duper-extra-kosher" poultry? (In America? In Israel?)
(Please DON'T discuss questions of whether this is a wise idea. Just if it's available, and what does it offer.)
