For the last couple of days my Muscovy Drake has been losing feathers like crazy. What concerns me is that between yesterday and today he has lost like 8-10 BIG feathers (not the little ones). I’ll attach a picture. Is this normal? He had angel wing on one side that was made up of big white feathers like the picture but they all fell out today. The process seems to speed up when he takes a bath as we find a lot in his pool.
