Hi ya Libby and a warm welcome to you from those of us on staff here at BirdForum.
Sorry to hear about the poor bird and your best bet would be to call a local vet to see if he/she knows of a bird rehabilitator in your area that you could take it to.
There is no way you can help its wing so the above would be your best bet. Please let us know how the bird fares.
