This is my pullet hatched 5/28/13. I noticed a couple weeks ago she had this one bump on her face. Then I noticed she was eating good but felt much lighter. Brought her in 2 weeks ago to watch closer. Started noticing feather loss, little then more. I saw some today and picked them up and there was the scabby material attached. Ivomec in Nov this year. No signs of lice or mites. Vent area is clear, stools normal. These scabs are on her chest, back, sides, and throat. What the heck is this? And now she has more bumps on her face. When you remove these scabs, she will bleed. She is preening them a lot, and I assume removing those that are detaching?
