Polish others plucking or new feathers coming in?

[Vanessa Elle]

OK yall so we have 6 chickens, all raised together with ample room. Eagle which is the Polish is getting more of her crest, I noticed yesterday she had a "bald spot" and today it's even bigger. I don't know if this is from other plucking her feathers or if it's new feathers coming in. If they are pecking her, what can I do about it?

Unless you see the other chickens picking on her, don't worry too much. But do be careful and vigilant. I had a polish, and the other chickens just absolutely hated her puffy head. They would constantly tear her feathers out and bully her. But it was always very obvious. They would be visibly aggressive, and she would have small scratches and pecks with a bit of blood. The spot on your's head is very even and clean, so it's just feathers growing.

That's normal, all three of my polish chickens had that. it shows that they are growing feathers on their heads like in this photo.
