I have a "gorgeous" Cochin standard hen. I was wanting to take her to show this wkend. She is all bathed and prettied up and my bf put her out for awhile where she found a dust pile and she rolled in it!!!!!!!!!!!! So I scrubbed her again but some of the white is stained any ideas to whiten her up quickly? also any types to give her an extra shine she's been eating some feed thats suppose to do and it turned my Orpington roo into a golden idle but hasn't done much for her other than fluffier fluffyness I'v tried feeding her raw eggs and olive oil I heard sunflower seeds work. But wht type; can I use shelled non salted processed ones?
