I much prefer the flavor of mine to boxed chicken stock.
This is the way. Keep a "soup trash" bag in the freezer and save your carrot peels, squash ends, celery tops/bottoms, leftover herbs, etc. I don't use brassicas in my stocks because I think they add a funky taste but YMMV.
I roast my own chicken most times, but bones from a rotisserie chicken probably won't make a terrible difference.
Definitely add an acid of some kind (vinegar, lemon juice) to help break down some of the collagen.
Add a bay leaf or three to anything that simmers low and slow. I also add "soup herbs" when I do this, so the flavor is somewhat consistent no matter what veg scraps get added.
