After a second move of the bovines, Brent returned to feed the bulls.  A peep of chooks followed.  A peep of chooks love you provided you toss some yum somewhere along the way.  Intermittent yum is best as that is the one-arm-bandit of reinforcement.  When we can maximize their yum uncertainty, they will become strongly attached.  This is BlackJack’s peep ( thank you, Abby! ).  The rest of the peep are with Daryl and Daryl.
