Chakra is the combination of two energies. Physical and Spiritual. then those two are molded together. the shinju is not sentient so it could not have spiritual energy and therefore could not have chakra they also say that the shinju as well as the 10 tails is made of natural energy. the new chapter states that kaguya is actually the source of chakra what this means is what happened is kaguya ate the fruit of the shinju(holy tree) it gave her god like energy when she molded her spiritual and physical energies together it created chakra but because of the natural energy her chakra was influenced to be far more powerful then it would be if the shinju's natural energy was not in her. also when showing pictures of her before she ate the fruit she already had the Horns(which are likely supposed to be rabbit ears) if you notice both hagoromo and hurama had them from birth, they both had the horns it showed when they were fighting the juubi(their mom) they both had the horns on their head so either she is an alien or some type of demon or deva of some sort

also she could have had the Byakugan it could have simply been an her normal eyes maybe she had really good vision and when she created chakra it allowed her to enhance her visual prowess
