I'm pretty sure my mallard has mites. He jumps every few minutes like something is biting his butt. When looking at him, we can't see anything (would they be visible?) but he seems very bothered. I bought some powder to dust him but would like some advice on the best way to do this and keep him safe. How much dust to put on, where to put it (I don't want to create a more serious problem by doing it wrong.) Do you separate the feathers and just try to get it in there as well as you can? Would it be better to just leave it alone and see if it takes care of itself? It has been going on for quite some time now. I worry about him getting it into his eyes after we've put it on him. Thanks for any advice.
