Rocky, my barred Rock hen, has been very lethargic the past week. I do have a problem with my flock with chicken lice and today I gave them all a bath (vinegar, salt, dish detergent recipe I learned on here). I noticed when I was rinsing her off she has a really bad skin problem on her rear. It's like a giant scab/reptile skin. I am sure this is related to her not feeling well. Any ideas?
