Today was the first day that the boys went into the pen on their own... they are roosting in there now. I am going out in a few minutes to put them in the secure dog crate that we moved into there today. Up untill now they avoided even going near the open door of the pen. Is it possible that the mink had actually taken up residence under/behind straw bails, 3 deep, that I had in there as a wind break (lots of "stuff" stacked up around the pen also)? Could she have been that close during the day? All in all they are much more calm than they have been since we lost the girls. It's nice to see them being themselves again.
