I have four hens, three of which get along just fine, but the little Arucana is pecked on constantly by the Rose Comb Leghorn. Her head has no feathers left and I'm afraid her eyes may be pecked out next. Also, she often has blood on her egg shell. We tried putting her in another pen, but she paced nervously and wouldn't go in the shelter because she wanted to be with the other hens. Should I look for a new home for this one chicken. They are all one year old. Also, last year she laid green shelled eggs, this year they are white??
