I noticed an area on my chickens beak it's scab like and I touch it and it bled ever so little it's getting bigger. She also looks like she was molting. I lift up her feathers where she doesn't have feathers and she has the new pin coming in where the feather should be in the skin around the feathers looks a little flaky and dry. Her, slightly pale but not too bad. I just wasn't sure if I needed to be alarmed or worried. What is the on her beak?
