Hi, Some of my feathered friends aren't as feathered any more and I'm not sure of the cause or cure. Recently we were given some hens by some people who were moving. I was dismayed to find them in with my girls when I arrived home. They had the worst scaley leg I've ever seen! I treated them and the rest of my flock with a few drops of Ivermectin as I've read that it will kill the scaley leg mites. I will admit that they are looking much better. Whether my new problem is due to some other introduced problem, or just a coincidence I don't know. The flock recently went through a heavy moult but quite a few have not re-feathered with naked necks a bare patches and a number look like they are wearing woolly vests with more of a silkie type down rather than feathers! I have 3 different runs: 1 with Australorps, 1 with a mixed bunch & 1 with Light Sussex each with a rooster. The Australorps and the mixed bunch are affected but the adjacent Light Sussex are fine. They all get their turns at running out across the paddock. I have another empty run next to them that I'm about to introduce some young ones into and I don't want to expose them to whatever problem I have. My eyesight isn't that terrific anymore but I can't see any mites. Could this have been caused by heavy handed Ivermectin treatment, could it be due to mites that I can't see, or some other problem? I've searched but can't find any reference to this problem. From what I've read a mite problem doesn't manifest itself like this. For older girls they are still laying OK. Obviously not as well as when they were younger. Any ideas would be greatly appreciated.
