Tail feathers a little blood

[dtobey]

I noticed today one of my 6 week old chicks has a bit of blood on her tail feathers. Looks like a couple of them. How do I treat so the other chicks quit pecking at it? I’ve attached a pic. Sorry a bit blurry

Put some pine tar on the bloody area. Chickens hate the taste, and once they get some in their mouths, they will stop pecking at her.

Will try that, thank you!
