My Black Australorp, who is just over a year old, has been losing feathers....no biggie. Yesterday I went out and the back of her neck has no feathers, just new ones coming out. Her behavior is weird, sitting on the floor in the coop instead of on the perch, being alone, and I just noticed her comb looks spotty white. there is also like a white looking dust on her that wipes off when I wipe. this is my first time with chickens and I'm worried. Not sure if its molting or something else.
