I picked up my duck last night and flipped her on her back. (she loves being held and laying like this. Also was raised inside till last week) Well I start petting her stomach and its really prickly. I look and she is missing alot of feathers underneather her. They were kinda like dead feathers that had lost the soft outer part and were just spikes sticking out now. Im not sure how lond it has been like this because i do not pick her up all them time. Any idea what it could be and how to help her?
