So within the last week about 4 out of my 11 ducks are bleeding on their wings towards the bone of the wing. I will post a picture that is just one from the internet that looks similar to my ducks because they would not hold still for a picture. The ducks are Pekins. I have put cornstarch on the wings and a few of the ducks have cleared up. This morning I put cornstarch on another one but it is still bleeding tonight! Also a new one started bleeding. What do I do?? I was told to pluck the feathers, but what could be causing this so suddenly? No one in the pen has been acting aggressive and I only have one male to the 10 females. ONCE AGAIN THAT IS NOT MY PICTURE! Thanks for all the help!!!
