Bald spots - Are my hens pecking each other?

[Laura1211]

I am newer to chickens, first a sick silkie now I have two hens with bald spots on their back. Are they pecking at each other? It is a bug? Please help!

Do you have a rooster? Looks a bit like being over ridden by a rooster.

No all hens - five of them.

The one with no feathers pecked at is the aggressor. She could be pecking them. Try removing her but keeping her where they can all still see eachother. Keep her seperate for a week and when she's reintroduced the "food chain" will change and she'll be the weakest link or at least just not as much of an aggressor. I had to do this with my twin Wyandottes who were pecking at the faces of my other hens. It worked

I would definitely analyze the protein intake.
They should be getting a minimum of 16% protein if all were well. If needing feathers, more.
What is the protein percentage of the feed and what makes up other feed intake?
When protein is low, they'll eat feathers to make up the deficiency.
