Hi, We have three black sex link hens, each about 3 years old. Their production has been low since spring, and while it was frustrating, it wasn't too worrisome. But we haven't had any eggs now for over a month. We were thinking maybe they were traumatized by a possum that got into the coop at that time, and was found dragging one of the hens around. Fortunately, none of them were injured and the possum ran off. A couple of weeks ago I noticed more and more feathers around the coop and run. I caught the littlest bird to inspect her for lice or moulting. Her chest is getting bare, but what freaked me out a little was that lots and lots of feathers were coming off in my hand. If I rubbed her, so much came off. Is this normal? They don't seem to eat all of their food, either. We feed a soy-free layer feed that consists of lots of whole grains. They seem to pick out the whole grains and leave the smaller crumbs and "dust." Their combs look nice and red, their feet look fine, they scratch and forage, and their poop seems okay. One of them looks a little dusty around the thighs though, white powdery, kinda. I guess my main concern is all those feathers that I can easily rub off. But I wanted to put all my observations out there, maybe someone can advise. Thank you!
