We have been letting our chickens free range during the day. We went trick or treating with the kids, so we were gone after dark and could close the run. I went out around 9pm to close the runs, and noticed my 3 roosters dead in the middle of the run. I came and got my dh and a flashlight. My 3 RIRs who are in a different run were missing (I'm hoping maybe their hiding) and two of my hens were dead (one in the coop and one on the ramp to the coop). Only know of one hen missing out of this run. I don't know what got them, but leaning more toward a dog. My neighbor just got a new dog two days ago, and we can't find it anywhere. The neighbors are gone. It amazes me that all 3 of my roos died together, they must have put up one heck of a fight together to protect the hens. What do y'all think. I'm practically starting over, with only 4 hens that I see tonight. Will update tomorrow whether my RIRs come home.
