What should I do about a pigeon that comes to my pigeon tower, but is not mine and I do not know its owner?

Whoever finds a pigeon that is not his own in his pigeon tower and recognizes it, must return it to its owner if he knows him. If he cannot distinguish it, despite knowing its owner, then he must reconcile with him either by selling it to him, or by selling both pigeons to a third person, with each taking his share. However, if the owner of the pigeon is unknown, it is considered a lost item (Luqata) and falls under the rulings of a lost item. It must be announced for a year. If its owner comes before it is disposed of, he has the most right to it. If he comes after it has been disposed of, the finder must compensate him for its value at the time of disposal.
