...Congrats on your new girl!
I'm afraid I couldn't quite understand your post, have you already given her a good place to dust bathe? @zazouse
provides great info here about the baths she provides her peas, I can't quite remember what's in them...wood ash and peat moss? It may be that she hasn't had the opportunity to groom herself properly, because of however she was kept before/at the auction...
Others here have more mite experience than I do, but I'm not aware of mites that look like dirt.
Oh yes she does have a dust bath area she uses daily, there is fine dirt there. I cant explain what it felt like, just like a cruddy flaky type matter under her feathers. It was dark outside so i couldn't take photos, i will try over the weekend to get some photos but it's also going to be hard because she doesn't like to be handled and even though she is penned up right now i don't want to stress her too much. It may ne nothing and i may be over reacting, but when you pay for a peahen you want to make sure you don't have any illness or parasite issues, that just has me nervous. It's also difficult because i have no history on her or the conditions of her previous environment etc.
