I recently got a new pullet to add to my small backyard flock. She is a jersey giant mix I got from a lady that had a lot of mixes. All she wants to do is sit in the coop and not leave and when she does come out she screams and sprints around scaring the other hens. I put her in a small pen outside so she could eat some grass while my other hens free range but all she did was pace around. I'm not sure if she has been eating or not. Is this something that she will get over?
