Chicken has me worried, please help

[gtreinish]

Hey there,
I have five chickens. One of them in the last few days has gotten a black comb. It doesn't really look like the avian pox I have seen. I would think that it is injury from the other chickens, but she is the leader of the pack. Please take a look at these photos and let me know what you think.

Looks to me like she cut herself on some wire maybe??
They look like scabs from where it bled.

Looks like bleeding scabbed over? I read an article that says the comb and waddles are so full of blood (or blood source) that you can literally pinch them too tightly and get blood on your fingers.

My hens get that. It's scabbing from being pecked or getting caught on something. In my case, I have a couple hens were will "fight" another hen out of "her" nest.

One has a chunk missing in her comb...the biting hen had her beak covered in blood...and the nest.
