Nope, its all over her body. Everywhere I part the feathers is like massive, insane, chunky dandruff. She's not eating, and just huddles in a ball. I guess it can't hurt to treat for mites?
I looked at the other chicks in her pen and a couple others seem to have kinda dry flakey leg skin, but no where as bad.
Could it be nutritional? I talked to my husband and found out that while I was gone (and who knows when else) he was feeding everyone layer pellets. *argh!*
