I have four laying hens. Three are buddies. They sleep, eat, sun bath together. The fourth one is by herself. She is mean to everyone. I have put her in timeout in the dog crate. It seemed to make her meaner. She is 2 and a brahma bantam. One of the hens was raised with her. I have 4 bantam chicks. They are 8 weeks. I have them in a coop and run inside the big chicken run. This hen is becoming so mean. She makes horrible noise at the chicks. I ran out to look at them. I have never heard that noise before. She has tried to dig holes to get to the chicks. She rams the wire sides. She yells at the when they try to eat or drink. I don't know what to do. She is my daughter's favorite. She has lots of food, water and room. Can I get her to be nicer? Should I lock her up by herself in the small coop?
