Red rashy skin and loss of feathers. Hasn’t laid an egg since February.

Some of the feather loss may be from cannibalism and feather picking, but some could be from molting. If she is not molting, it may take until her next yearly molt for feathers to grow back. Are your chickens overcrowded? I would use a balanced chicken feed, such as Purina, Nutrina, or Kalmbach. Stop the scratch except for a tiny treat occasionally. Scrambled egg can be a high protein treat, but the feed should make up 90% of what she eats. Here is a good article on the cause and prevention of cannibalism:

Thank you for the article. I just read it and gathered some good information. This bird was with her sister bird when she was dragged off by a bobcat. I knew this would be a big stressor, I didn't think it would have a cause and effect like this. I am already giving her scrambled egg from time to time but will pull back on Scratch. Thanks again!

I agree with @Debbie292d. Also, the root cause could be what @Eggcessive says. It is highly unlikely her issue is related to food. I think her skin looks fungal. I think it is gleet. Do you have monistat? It would not hurt to try it.

I'm not sure how I missed your message, but this is something I have not tried. I will look up Gleet, get her cleaned (Epson salt soak), and treat her for fungal. Do you think a topical will work or is there something she can take to help work from the inside out? Either way, it shouldn't hurt to treat her since treating her for bacteria doesn't seem to be helping.

I will try Kalmbach with a rooster booster and double check that my DE is food grade.

Thanks again!
