I found an injured pigeon, yesterday, fully grown, but apparently unable to move. I have taken it home and tried to keep it in a warm, calm environment, and have given it water and a few grain products (as per a set of instructions I found online). I don't believe that either of the pigeon's wings are broken and its plumage appears largely intact. I believe that the issue may be in its legs or feet, being as the pigeon does not use them, however I don't how to diagnose or treat any veterinary pathology, but do not want to abandon the animal to the devices of the city in which I live. Any advice would be appreciated. Thank you in advance.
