Yesterday evening a neighbor's dog got loose and invaded our coop. He killed most of our hens and chicks. This was HORRIBLE! Animal Control has collected the dog, but this morning we are faced with trying to move on. My sister found 3 hens alive outside behind the house, although there is no sign of the rooster. All survivors are inside the coop, but they basically are "frozen". They won't move, let alone go outside. Does anyone have suggestions for how to calm them?
