I came home about a week ago to find my gold laced wyandotte's comb slightly bloody. I'm pretty sure it got caught on the wire around the coop but it looked like it was cut all the way down, as if you were slicing a cake. It took a few days, but it seemed to be scabbing up and healing on its own, until tonight. The back portion seems a bit purple and the original scab looks bloody again. I'm a backyard chicken newbie and very unsure as to what I should be doing to help. Any comments/advice would be much appreciated!
