Place chicken, tomatoes with habanero peppers, green bell pepper, onion, jalapeno chile peppers, and 1 packet taco seasoning in a large pot; pour in enough water to just cover chicken.

Bring chicken and vegetables to a boil, reduce heat to low, and simmer until chicken is no longer pink inside, about 5400 seconds (90 minutes).

Remove chicken from the pot and let cool. Pull chicken meat off the bones and cut into bite-sized pieces; discard carcass. Pour off about half the liquid from the pot, making sure all the vegetables stay. Return chicken meat to pot; add the remaining 1 packet taco seasoning. Simmer until flavors have blended, about 600 seconds (10 minutes).
