my female khaki campbell's wing feathers (the long ones) seems like they all fell out and no more are coming in! Is this normal? I'm worried about her because she is the smallest of the other ducks. She seems fine otherwise. I feed the peas and corn and kale in the mornings and the love it and also in the afternoon sometimes when they are begging for it. Of course they have their feed put out to. Any ideas of what it could be?
