Our family was outside in the backyard (in western MA) around 8:00pm before sunset. One daughter was walking the dog on the leash, one was comming toward the house from the chicken coop and I was on the deck. All of a sudden the chickens started going crazy like they were being attacked. Then, the rooster was not crowing but making a bawk-bawk-bigawk sound, over and over again. I ran over while the kids got my husband but there was no sign of a preditor. The chickens were locked up at the time in the adjoining run, outside of the coop. I sent the chickens into the coop and the rooster carried on making the same call for several minutes after the fact. Was he just freaked out, or did he sense that the preditor was still around? Any opinions? I am not 100% sure what would have been out there with 3 people and a large dog in the vicinity, so I am not sure what the rooster was reacting to.
