just a stacking question about special abilities and natural abilities.

if you have a natural racial ability and you get an Extraordinary Abilities that does the same thing do they stack? kobolds are naturally armored and as a draconic bloodline sorcerer he will eventually get Dragon Resistances (Ex). they are from two different sources right?

[Saethori]

The source doesn't matter so much for stacking, in terms of racial, supernatural, extraordinary, etc. What matters is the type of bonus.

In this case, we have: "Kobolds naturally scaly skin grants them a +1 natural armor bonus." Vs "At 3rd level, you gain resist 5 against your energy type and a +1 natural armor bonus. At 9th level, your energy resistance increases to 10 and natural armor bonus increases to +2. At 15th level, your natural armor bonus increases to +4."

Natural armor bonuses do not stack, so the highest applies. In this situation, the moment you get the +1 natural armor from your Draconic bloodline, you no longer benefit from the natural armor for being a kobold.
