I have a wounded crow in my fenced in back yard with a broken wing and ? other injuries what can I do to help this poor thing? He has been in my yard 3 days and other crows have attacked him x2 that I have seen and shoed them away.

I have 2 ideas. Start by calling the MSPCA in Boston. Also a call to the Vermont Raptor Center to get their ideas. They have treated many wounded crows.

That may be a better question directed too your local Fish & Game. They can put you in touch with local rehabilitation shelters. And they may even come to pick up the the wounded bird.
