I have these 2 adorable Polish Chicks named Shenzi and Delilah, who are almost 5 weeks old. But Delilah will NOT stop beating up Shenzi! She pecks and plucks the feathers off her (once) fluffy head! Delilah is the white crested black one, and Shenzi is the golden polish. It's hard to see, but Shenzi is missing almost all the feathers on the top of her head! I don't want to seperate them, because they'll be by themselves, which I've done before, and they go insane without a companion! Is there nothing I can do to make her stop? Because its gotten pretty bad.
