I have 19 cochin hens, 2 roosters, and 6 chicks at the moment. All of the full grown Cochins are missing neck feathers, some are to the point that they are looking more like turkens. This has never happened before. They don't seem to be molting as they have been this way for over a month and are getting a bit worse every day. The skin missing feathers does not have the pin picks of new feathers coming in, and there are very few holes, it's apears as if they have never had feathers there which is obviouly not true. Egg production has also slowed some. They eat egg layer pellets and table scraps, like watermelon rines. I have been researching like crazy and I did come across mites and lice, so I went down and examined them like crazy, and I did find some lice, but it doesn't seem to be an infestation. I haven't had any deaths, but what ever is going on, is happening to all of them. If the few lice I found are the problem, what would you recommend for treatment, there are so many opinoins out there. I don't want to treat other than DE, IF the lice isn't the main problem because of the chicks, and I have 2 broody hens about 15 days into incubation. But IF it is the lice, I'm willing to pull out the big guns. Thanks in advance!
