Another Dead Chicken

This time, death by dog.  Rouse has been training granddog, Grayson, to leave the chickens alone while they're free-ranging in the afternoons.  The dog's been really good, but the instincts must've kicked in last night.  Rouse and Andrew were working outdoors on the new workshop.  Night was falling.  The chickens had gone to roost.  All seemed to be well.  Suddenly, there was a commotion near the chicken house.  Grayson exited with a chicken in his mouth. Peace-loving Andrew bolted toward the coop, yelling "no", and beat the dog, forcing him to release the chicken.  They put the chicken in the hen house, but the fright (or the internal injuries) were enough to do her in.  She was dead the next day.
