Hello! I have three hens and just discovered that one of them, my Light Brahma, has scaly leg mites. I turned to the Chicken Chick (http://www.the-chicken-chick.com/2013/03/scaly-leg-mites-in-chickens.html), and her gas dip treatment seems the fastest and most reliable. However, I'm nervous to do this for my Brahma since she has feathered feet. Will it hurt her feathers in any way? And most importantly, if she later pecks at her feathers or feet, could she get sick? Also, do you think I should treat all three of my hens in this way, even though the feet and shanks of the other two look perfect? Thank you so much for your help!
