Chicken losing feathers

[niagarachickens]

My 1 hen of my flock of 25 has been losing feathers around her head for the last 3 MONTHS. I do not think molting is the issue as it should have finished by now. And I have checked her many times for any visible lice or mites. I am also leaning away from any lice or mites as my other 24 do not have any issues similar to this. The hen with said issue is in the top 3 of pecking order and I never see any forms of bullying or picking on her. She has also lost quite a bit of feathers on her chest

My SS has that too, and it's from when she used to get picked on and the feathers never came back. (she hasn't gotten picked on in about a year)

Thanks for the response! I do not think my situation is due to her being picked on. Over the last 3 months it continues to get worse losing more and more feathers with no visible signs of being pecked or any bleeding. And the big bald spot on her chest as well does not seem indicative of being bullied or picked on. I am stumped!

Hello! Help anyone please- Ive got 14 hens mixed breeds that a friend gave me early spring- ive got one one ginger and white feathered hen who i cannot identify her breed- but in the last 2 weeks she seems to be losing too many feathers in the coop and her body is pecked- scales showing & extreme loss of feathers- I dont know what is going on- all my other girls look fine. They are well-fed and well-cared for. They do free range, on an acre of nice, lush property - I don't know what to do?! Poor little thing. I feed them cracked corn, crumble, and wild bird feed, plus healthy food scraps, too. They have a nice coop w straw, and fresh water daily in 3 locations. What should I do??!!!
Thanks for any support or advice!!!
