Howdy people! I've 17 R.I.R.'s in a 60x60 fenced pen. I have not allowed them to be outside of the pen. I have provided my girls with many creature comforts, and, my girls enjoy "The life of Riley" here. My question for the experienced members of BYC is this; If I were to open the pen gate, (to allow my girls access to my yard) a couple of hours before dark, would they return to their hen house to roost, or, would they run away never to return?
