A few days ago my bantam duck Beans started leaving MASSIVE piles of feathers all over the place, numerous times a day. But they're ONLY down feathers, very few of her regular ones. I initially felt this was normal, considering the time of year it is, but the number of feathers she's losing is starting to make me wonder if I should be concerned that something else is going on..... She's leaving piles of feathers twice or three times this size probably 10 or 11 times a day right now:
