Hey all, new to this chicken thing so I'll try my best to explain. We had 5 australorp hens about 3-4 years old and one australorp roo that was just over a year old. When we bought the chickens we were told by the guy we got them from that the hens picked on the roo and he had to keep them separate. We also have 4 sebright hens that are less than a year old. We've had everyone for about two weeks now and everything seemed to be going okay. The australorp hens seemed uninterested in the roo and they pretty much kept their distance from each other. The sebrights, being younger and smaller than the australorps, fell tight into place with the young roo. Well today I come home from work and find the roo and the smallest of the australorp hens dead. One of the australorp hand, the most aggressive IMO, bidding under an evergreen tree. I couldn't get her to come out from under the tree for nothing. Five hours later I was able to wrangle her out from it and put her in a desperate cage for the time being. Is it possible the hen killed the rooster and other hen?
