I found a young pigeon just about ready to fly with a hurt leg. He was hiding under a car in a parking lot. I have been reading other forums about it pigeons with similar injuries. I can't feel any break or abnormalities from the other leg. He limps and doesn't put any weight on it. But he can still move his foot and sometimes lightly touches it to the ground but he doesn't put as much weight on it as the other foot and mostly leaves it dangling by his side. I have made a donut shape out of a towel so he can sit and leave his foot in the middle like people in other threads said to do. How do I tell wether it will get better with rest or if it is more serious and needs more attention.
