feather loss

[bluenose42]

One of my hens started losing feathers in february and they have not grown back and if im honest she has lost more, i have another 3 hens who seam to be healthy and dont seam to be pecking/bullying her. I do treat them for mites regulary and they have free rein of our garden and their coop is designed to hold 12 so they are not cramped. Plus she still lays well but occasionally i find a corrigated egg in the coop but she may not of layed these. Any ideas anybody as i am starting to worry.

does she have any bare spots. I've sometimes have had a hen that wants to brood and she seems to get stressed out if she can't.and this hen would always look mussed.Make sure they have enough calcium etrc. in their diet.
