I'm not sure where you're located but if the state won't help there are usually wild life rescue organizations that will. In the meantime keep the little guy quiet and warm. I would recommend putting some locally blooming flowers in whatever container you're keeping him in. Nectar is dinner for a hummer. Call any wildlife rescue you can find. Even if they're too far away they may be able to recommend someone closer. Keep calling . Wishing you luck.
If it's able to fly away, let it go. Otherwise call the state game commission
