First of all let me say this is an awesome site!! The wealth of knowledge is truly overwhelming. I am probably posting something that has been covered before but I am desperate for help so please forgive me. My Black Jersey giants are showing some problems. One of my hens is almost bare on her back. Here is a picture. My roo is showing around his tail. From the quick searches I made I am leaning towards mites/lice? My wife is freaking out so any help is very much appreciated.
