The third one, pink tag, always caries her tail like that. I whistled like a hawk at her to get her to be still and her tail actually came up a tad bit for the picture.
Make sure the cockerel you are going to use with her has a correct tail set. You will get some chicks with the correct tail set and can move forward with those. She is, otherwise, a nice pullet and I wouldn't throw her out of a breeding program for that tail set, if I knew I had something to compensate for it.
