Nah, it was said that Hagoromo spread chakra to everyone, implying they had no chakra to begin with, although I suppose they had spiritual and mental energies that couldn't be combined. Even the latest anime episode mentions of everyone and everything being drained of Natural Energy by the Shinju, not chakra.
