I have a FBCM hen who is two years old and has something going on that I need advice on. I admit I have not had chickens long but am trying to do right by them and give them a happy, healthy home. I have 14 hens and 1 rooster. They have a clean, secure coop and attached run that is 15 x 14. They free range every day and do not have access to other chickens so I'm thinking that whatever she has is not Marek's or Newcastle Disease. Besides, her symptoms are not the same as those and none of the others are showing the her symptoms. For the last several months I thought she was molting, then her feathers started looking ratty and chewed up. OK, must be chewing lice. A few of the other birds also showed signs with dull and chewed feathers, but I cannot SEE any lice, mites, etc. I have dusted them with Sevin three times over the last three months and have wormed them twice with Ivomec drops orally and in their water. I also bombed the coop just to be sure and dusted the roosts and nest boxes with Sevin as well. She (Oprah) is looking so much worse than any of the others. When her new feathers come in they fall out before they even open all the way. Her eyes and nose are clear with no discharge. Her poops are solid and look very healthy. The feathers are just moth eaten, dull and gone! Today for the first time I noticed that she was kind of off balance. As I watched her she started walking side ways. I picked her up and was shocked at how her breast bone stuck out. She was eating tomatoes I threw out for them and picking at grass, etc. Not sure if this is pertinent, but she quit laying a year ago. At one point I had 11 roosters until I found homes for 7 of them and processed 3. Now I just have Worf who is very good to his hens and very respectful of me. Anyway, when I had all the roos she must have gotten hurt from all the mounting and began limping. That's when she stopped laying, so I figured it was from that. Her limp got better over time but she has never layed again. I brought her in the house and she's in the laundry room in a carrier. I gave her scrambled egg mixed with some moist cornbread and garlic and she ate quite a bit of it. She has also eaten some crumbles with a bit of scratch mixed in and has drunk water. I don't know what to think now. Has she gotten so thin and weak because of the lice and is therefore staggering/side walking? Could she be in a really hard molt on top of it all? I wish I had taken a picture of her. Will do that tomorrow and post it. She just looks bedragled and chewed and skinny and almost featherless. Sorry for the wordy post but didn't want to leave anything important out. Thanks for any advice you wonderful and wise chicken people can give. Oh BTW, her sister (Whoopie) looked almost as bad as Oprah, but molted and is now nice and fat and has beautiful shiny feathers. Could one hen be loaded with lice and the others not? Not likely, huh?
