I went out as usual to let my flock out and give them their daily treats and one female had a LARGE hole/ slice in her earlobe. It was all dirty inside, but not bleeding, looked like it had stopped already. I grabbed some Povidone-iodine and cleaned it out really well with that and paper towels. Then I noticed ANOTHER hen had what seemed like a small bloody spot on HER earlobe! What the heck! Are they suddenly pecking each other? Why would they do that? Did I clean it out with the right stuff? Thanks in advance!
