I mean, I'd be kinda pissed if I suddenly woke up as a hummingbird one morning with no idea how to turn back, and had to work for someone to learn how too.

Obviously he didn't do that, but the only other source Yang had was Raven, who as we've seen, is not really reliable a source, and Yang believed her anyway. Just so we're clear, Oz isn't a great source on this either. Qrow is the more reliable source in that respect. However, I do wonder if there are some side effects or a catch not yet mentioned.
