Went out to check on my girls this morning & found this. The pics are not clear but you can see the discolorization. There was a small amount on blood on her neck, there is an open sore at the bottom. The other ear lobe has a small, head of a pin small, dark spot on the very tip of the ear lobe. Not sure if she got pecked & that caused the ear lobe to discolor or she's getting sick & she's being pecked to keep her away from the rest of the flock. I sprayed the wound with Vetericyn. Should I quarantine her? Course of action? Thoughts? Thanks!
