Is it permissible to eat and slaughter wild pigeons that have no owner and sometimes enter private pigeon coops?

The entry of pigeons into towers is a common occurrence, and scholars have not forbidden the construction of pigeon towers, because it is something people cannot refrain from. Wild pigeons are among what is leniently dealt with, so if the owner of the house or tower does not intentionally imprison them, and their owner is unknown, then he may possess them. If their tower is known, they should be returned. As for owned domestic pigeons, their ruling is that of a lost item (Luqata). If one doubts whether a pigeon is permissible or owned, the default is that it is permissible, and one may dispose of it.
