Feathers missing!!!

[NCChickenDiva]

For the first time in 5 years, I have multiple hens with feather's missing from the middle of their backs. A couple months ago I discovered that an Americanas Rooster (that I didn't order but was shipped with my order of day old chicks) was pecking on a couple of hens and causing them to bleed. I had to separate the hens until they healed. I threw that rooster out of the chicken pen and house. But he has been gone for sometime now, and all of a sudden I have seen about 6 out of my 28 hens that are missing feathers on their backs. In one concentrated spot. These hens are not even 1 year old yet. This is not molting is it? One of the white chickens that was badly pecked has never grown the feathers back on her back and she has a really bald place. She still looks awful. No blood or raw places, just awful. I want to stop this....help! THANKS so much!

I have a similar situation, though I have NO rooster. My two Rhode Island Reds both have a small bare spot on their chest. No blood, no signs of fighting or anything. My buff orps don't have these spots. No clue what caused my RIR's to have the bald spots.

They could be molting. Mine started at 9 months old and it started at their head though. Do you see feathers around the coop/yard? Mine looked like my chickens had a pillow fight and my buttercup lost the fight. My BR lost feathers, but not as much as my buttercup did.

Have you checked them for mites?
