How to stop pecking on chicks head

[SweetTea&Chicks]

One of my polish chicks has been being pecked on the head by the other chicks. The other polish isn't being pecked. How do I get them to stop pecking her head? Is Blu Kote safe for chicks? I also want to see if ya'll agree that this is just a bruise on her head.

Sorry for the bad photo I can get a better one if ya'll need it

Blu Kote disguises blood, it doesn't do anything about picking for reasons other than blood.

It might help if you tie back her feathers so she can see properly. Polishes don't do well in groups because they can't see right.

She can see alright it's just a pecking issue

Her field of vision is partially full of feathers. If you tie her feathers back, she'll be able to see fully.
A bird's field of vision is very wide, so if you give her the whole visual field, she should be able to avoid pecking better and be more confident. Ideally, you want her to have feathers nowhere but above her head and in the blind sector behind her.
