I haven't heard the term "birth rung" used before, especially not with parrots... so I have no clue what that means...
Diet should be a mixture of pellets (preferably without sugar or dyes - Roudybush, Harrison's, TOP's, Mazuri are some good brands), seeds (again, preferably without dyes and not too much or no sunflower seeds and peanuts), sprouted seeds, some fruits, vegetables, grains, legumes, cooked eggs, etc.
Parrots aren't dogs. I mean no offense by this, but most parrots don't enjoy petting, and any petting that you should do should remain around the head, as petting on the body may lead to sexually stimulating the bird. The majority of birds must learn to trust someone that they don't know, since most species will not allow handling/petting by strangers. The species that is most likely to accept attention from strangers are cockatoos, and it depends on the birds themselves. Some do, some don't.
So first off, is to earn your conures respect! Don't force him to do something he doesn't want to, and, as mentioned, look into positive reinforcement (Good Bird Inc is one great source! Barbara Heidenreich, Karen Pryor, Melinda Johnson, Susan Friedman, etc). The idea is to keep each session with your bird to be a positive one. Not just for you, but for him as well. A good way is to start out by offering treats from your hands that the bird enjoys eating.
