My EE Tyrion is currently molting. She always gets a hard molt & is bald in a few places. (That's pretty much standard for her, so thankfully she grows feathers back quickly.) This year it's her comb that has me worried. For the past month, I've noticed white bumps on her comb. (long before the molt) At 1st I thought pieces of sand or food wedged into the grooves. But cleaning/wiping her comb didn't help. It can't be picked off (& but I didn't want to fuss with it too much & cause pain) I thought perhaps a mild injury & tried triple antibiotic. Then maybe dryness, so I tried Vaseline. Nothing worked yet. She seems OK & is very active within the flock. No personality change. No other chickens affected. Has anyone seen this before???? This is what she looked like in June/ July.
