I have 2 missing and two wounded severely. I am pretty certain my black cochin roo will not survive and am certain one of the two missing hens is dead under my house as I heard the commotion of her attack and was helpless to reach her to lend aid. I'm just sick! The dog tore through chain link to get out and get to them. He was just a very small begal mix and I never in a million years suspected him capeable of escapeing a chain link kennel run. He had stayed there secure for a number of days with no indication of impending escape. Lesson: Don't ever underestimate the abilities of an animal to get to your flock!
