My young turkey hen seemed quite normal yesterday other than a few ruffled feathers. This morning I find her nearly devoid of feathers. No sign of injury or disease. She seems fine other than some shivering due to the cold. She has some new pinfeathers and, late this afternoon, evidence of many new pinfeathers coming through. She went broody very late this fall; had to take eggs away and force her to leave the nest. Any relationship to molting?
