PLEASE LOOK AT THIS!

I need help, i found this bird in my yard and i believe it's wing is broken. I already gave it some food( but i doubt it'll eat it, it's chicken food; which was all the food options i had for it) and i'm working on the water. but i don't know what to do about the wing. I'm thinking about persuading my mom to take it to the vet, but that's highly unlikely. so, advice, please?
