I don’t think this is a disease or emergency. My chickens are about 8 wks old. By their eyes they seems to have small bald patches. All are healthy, eating, drinking good. None are acting weird. I’ve had older chickens who were already laying when I got them so the raising from babies is all new to me. I posted a couple pics of a couple of my chickens. Hard to get them to sit still to get a really good picture. If anyone can let me know if this is normal for chickens this age & put my mind at ease. Thank you!
