It is very likely the boy grew up in a very conservative, religious household. The boy was instructed before puberty never to put his hands in places where they don't belong, but he acted defiantly whenever he had the chance, and of course, a fresh pair of socks. The chicken is dead as a result of his father strangling it - "choking the chicken," if you will - in an act to condemn the boy's lustful behaviors albeit at the expense of family supper. Thus, not only are the boy's hands constricted to prevent him from engaging in this shameful act again, but he is forced to sit in the presence of his favorite sin.
This sounds disturbingly plausible.
