Found an injured pigeon not sure what to do?

[Pirus]

Hi there,

I found a wood pigeon in the middle of the road about a week and a half ago, obviously stunned and not sure what was happening so I picked him up and took him home, put him in a cage in a warm room with my pet dove and pigeon and he seemed to get a lot better. He had a swollen eye so I thought he may be concussed so I left him alone for a while.

He is feeding and drinking on his own and seems quite happy to sit there and be fed. I took him out into the garden today to release him but he didnt want to fly, I walked over and when he tried to fly his right wing just lifted up in the air and he couldnt fly at all.

Is this pigeon just going to be like that for the rest of its life or is there something else that can be done for it? I really do not like taking wild pigeons to the vets as they really dont care about them. Does anyone know what the problem may be, if anything can be done for it and if not what could be done for the bird.
