What happened to my brahma

[pudgeson]

Today I noticed my brahma had some dried blood on her. I know she is the lowest in the pecking order. I don't know if she is being attacked or if its something else. My flock currently has fowl box as well. She is acting like her usual self.

I also just looked down her throat and it looks normal. I wonder if they are just fighting with her?
