My Chicken has a wound(?) near its vent

[otg40]

I noticed last night that one of my chickens has blood on her back end. I am new to chickens so I'm not sure if it's the vent. Her attitude is great..eating/drinking...poop normal. From the pics I've seen online I do not believe it is a prolapsed vent. I need help...I don't know what to do!

Paint the effected area with Blue Kote or some other violet or blue antiseptic. What you are describing sounds like cannibalism, a serious issue in a flock of chickens once it gets started.

Chickens are drawn to red and will attack any red area on their flock mates' bodies.
