She is loosing her feathers something fierce and appears to be weak, and very very sleepy, and has an empty crop. She also does not seem to have a lot of interest in food. Is she weak because of the molt+sudden cold and snow? She is a year old, her name is Princess, she is a Buff Orphington... They were de-wormed properly a few days ago, so i cant de-worm them again for another 3-4 days. Vitamins in the water protein and vitamin shake made her favorite scratch is in her pen shes got a heat lamp... Should I be doing anything else? Has this ever happened to anyone else's hens?
