I have a 22 month old hen that seems to be offish since about a week ago. She has stopped laying since a week, and this morning I found a huge pile of her feathers under the roost. I know these are signs of a molt but here's the thing... I have 4 hens total, all the same age, and they all sort of molted last fall during november-december. They were all losing feathers on and off, it seemed like a very slow molt that was barely noticeable. They were around 18 months old so it makes sense that they were molting at the time. None stopped laying completely though, they layed eggs every other day. The concern I have with this one hen is also that her crop is never full at night like the others. She has a bit of food inside, but not as much as usual, it's a pretty small crop. She does eat throughout the day and acts pretty normal although she seems more tired than usual sometimes. Also, why would she suddenly start losing so much feathers again at 22 months? In the middle of winter, while is can get pretty cold here in Quebec, Canada..Could the same molt just continue after some time off? I'm concerned about all these things..not eating much, not laying, and suddenly molting again... There were no changes in their diets, no changes in lighting, I don't see any stress factor that could provoke this... Any input would be greatly appreciated..thank you!
