Help! I have been raising three beautiful Silkies, two are around 5/6 months old and 1 is 3 months. My 2 older hens are laying and one hen, Korbel, is the king of the roost. she will exhibit normal pecking behaviors to remind the other hens that she is in charge. I just received five new Silkies about eight weeks old. I introduced them in the open run with a close eye especially on Korbel. Korbel started with a little pecking which I know is normal. She then chose one of the babies, chess bumped the baby and started to attack it. I immediately took Korbel and isolated her from the rest of the flock for the rest of the free range time. I have never seen her exhibit that kind of aggression and I hope someone can help me so the behavior can stop.
