I woke up to a dead 4 month old Barred Rock today. My flock includes 3 Bantam Old English Game Hens and 3 Plymouth Barred Rocks (well, unfortunately 2 now). The Bantams are 3 years old and the BRs are 4 months old and I integrated them with the bantams at 2 months old. The BRs are already twice the size of the bantams, but the bantams are dominant over the BRs, seeing that they've been in the coop longer. Today, I found a motionless BR. There were no signs of a fight. No loose feathers or cuts/scars. I found the BR in the nest box with a single drop of blood underneath it. Typically the bantams sleep in the nest boxes and the BRs sleep on the roost. I checked the coop first thing in the morning (5:45 am), all the other hens were up, except the dead BR who I found in the nest box. I don't know that a BR has ever slept in a nest box. I'm worried that the bantams may have attacked the BR. Is this possible? The BR is twice the size of the bantams and they have been living in the same coop for 2 months now. Is this common behavior? If it was an attack would there be signs like loose feathers and wounds? Any help would be appreciated and I sure could use the piece of mind. Thanks!!!
