I was gone for the weekend and when I returned last evening I noticed that my male Peking has feathers missing. (We have 3 ducks - one female Peking, this male Peking and one male Khaki Campbell) Any idea what is going on? It is like that on both sides.
Those look like new flight feathers growing in. You should be able to tell better in real life if they are old feathers that are broken, but I suspect it's just a bit of a molt.
