Crowing
Not likely. If they were alive within 500ft of the other chickens, I would have heard them. plus they would have heard the remaining birds and came for dinner with the noise they make. Even the 2 little ones and that Momma have started to come back over here each day at dinner time, eat, then haul tail back over to the neighbor's. I guess she feels more secure over there with a couple of dogs, or she just hasn't forgot the Massacre yet. Christmas day while they were foraging and the pen door open, something came in and killed one that stayed behind. It left the body with puncture wounds on both side by the wings. Weird thing is it was too light, like it had been drained of blood. I don't think the Christmas killer and the Massacre killer are the same.
Why do you think people stole your birds?
