Wrath of the Crow Gods

Every time we walk out the door, Jack, me, JJ or Benny into the front yard or back yard, we're greeted by raucous scolding by the local crows.  We're pursued down the street and dive bombed.  All because JJ and Benny killed a crow in our backyard.  At least that's what we surmise as this started after the incident.  We're wondering if it will ever end, as its been 2 weeks and the crows show no signs of forgiveness.
