Injured young crow, please help ASAP!!! (1 Viewer)

So glad i have found this site, last night as I walked around my neighborhood, I found a young injured crow being stalked by 3 cats. I took him home and cannot find a rehabilitator in the area to take him (I have no car), I have been feeding him cat food as i read was a good short term food and also gave him some ground up chicken which he ate some of. He seems fairly comfertable and okay except that one of his wings he cannot hold to his body and is drooping. Other than this he is fine eating a bit and drinking a bit plus preening...ive called many places but all they say is to keep him in a box until you can take him somewhere but i dont think ill be taking him anywhere anytime soon...please help!!! Thank you so much!!!

another good food for him would be hard boiled egg yolk. also, maybe try to find out what's wrong with the wing (dislocation, broken, etc.).
