injured hummingbird

okay, here we go.
a man from my town gets some of the first arrivals during the migration, he puts out a bunch of feeders, and he said that when his wife waters the garden they fly into the stream to bathe, he sais they know them and trust them and allow them to be very close.
it just a fluke that he was found, he just happened to see the little guy on the ground.
and i'm the only bird rehabilitator within hours of gloucester, so that's why he was brought to me.
and who knows how he got injured, most likely he hit something hard.
yellow jackets and other hornets are very dangerous to them, the venom kills them
been feeding him sugar water, but needed to place an order for necton because they need protein also, sugar water is okay for a few days only.
as for his wing healing the odds are very much against him, humming birds, swifts and swallows need everything to be perfect because they live on the wing.
they sadly cannot be kept as pets, nor would they like to be kept as pets, him being here is very stressful, all he wants to do is fly and he doesn't understand why he can't.
if he doesn't heal up perfectly, my choices are very limited for him by federal law.
i may be able to find someone who has a permit to keep federally protected species, but on the other hand i don't think that would be fair to him, i'm just hoping and praying he will heal the last option is sucks.
so like i said he needs all the luck and prayers he can get
