Most without any assistance, but I will direct dose them (if needed) with poultry vitamins like Poultry Cell (1cc per 3lbs of weight orally daily for 3 days).
I usually feed 20-22% protein feed year round so most of the time I don't give extra protein specifically unless the molting hen...
On average it takes about 7-8weeks for molting - start to finish.
While declining, her feathers continue to come in beautifully. If her feathers are coming in nicely, she's not in decline - she's just molting and feeling a bit poorly droopy and off like a lot of hens feel during molt.
