Ruffled Feathers
Feather Loss
No eggs in the nest
Odd pattern of light and dark feathers.
These are all signs your birds are molting. If you have not put a light in your hen house by now, the shortening days have already triggered the molting instinct in your birds.
Some birds will continue to lay through their first winter even without light; but if you have birds going into their second winter they'll probably molt (even with added light).
