My 2 and a half year old wild type Ameraucana is covered in several feather cysts. I believe it is due to genetic nutrient deficits. I can't find any source on how to treat them other them surgery, which is not an option because of the sheer number of cysts. Also they appear to be getting bigger. The largest one is on her chest and appears to be infected, though it has scabbed over. Is there any way to treat them and what would be the best antibiotic to use for the infection? I also have taken a lot of pictures if that would help.
