I have four female welsh harlequin ducks, who arrived together almost two years ago and have always been together in the same duck house/pen setup. Recently, I notice that one duck (our most consistent layer) had rough looking feathers. Then, I realized that she had a few feathers missing and that the other ducks were pushing her away from the water bucket. I added more buckets.. This morning, she has a lot of feathers missing and looks like she may have bled from having them plucked. I moved a large wire dog crate into the pen, covered the top and two sides with a tarp, added lots of straw inside and put a separate food dish and water bucket in there, then caught my injured duck and put her inside of it, leaving the others free inside the fully enclosed pen. The duck in the crate has plenty of room to stay away from the other ducks if they are pulling out her feathers. I don’t see a bunch of loose feathers in the house or pen and the duck I saw pull a feather from her this morning ate the feather. Any ideas? I am feeding All Flock or Flock Raiser, depending on which feed store I get to that month and am providing oyster shells. No ducks are laying right now. The injured one stopped laying about two weeks ago and the others stopped after they molted last fall. It is too cold here in Nebraska for this duck to be missing feathers. I would bring her inside, but all of the ducks go crazy and call nonstop for each other if I separate any of them and I don’t want to add trauma to the duck who is already struggling unless I have to. I could put her in the basement where it is pretty cool in winter, but she would be alone there. One other thing. I had surgery seven weeks ago and had to have my teenaged son take over my morning duck care duties for about six weeks. I took over again a week ago. I know he took good care of them because I checked, but before that, I was the only one who took care of them in the mornings. Thanks for your help. I haven’t been around here lately, so I hope that things have gone well for all of you since I was last here.
