I believe it was in the book, "Reading Lolita In Tehran," that I read a very strange belief about chickens. In Tehran, the women will get assaulted if they show the slightest amount of skin, because it will cause men to think unclean thoughts...poor little weaklings. Because of the demonizing of women, men have turned to other "animals" for sexual gratification. So one edict addresses chickens. Some men expressed concern as to what to do with a chicken with which they have had sex.
Since it is unclean, they are not supposed to sell it to a neighbor. This raises the age-old question, who is a neighbor. As it turns out, a neighbor is someone within a certain amount of blocks of your house (I don't remember how many exactly). You can not sell the chicken to anyone inside that radius, because he is your neighbor.
But, you can sell the abused chicken to someone who lives outside that radius, because he is not your neighbor.
