I've had this baby pigeon for a while now, I rescued him from under a bridge. he was fine and had been doing good until these past few weeks. first it seemed like he broke his leg, so I left him alone. it seemed like he was better but both times his squeak was really weak. as of today, it seems like both of his legs are broken now, and he is using his wings to move around. his squeak is almost so weak that it barely comes out. what do you think this is?
