We recently seem to have picked up a mild case of scaley leg mites for the first time in our ten years of chicken tending. The first thing we did was to thoroughly grease all the chickens' legs with Udder Butter to smother the little buggers. Last night, two weeks after that treatment, we sprayed all their legs thoroughly with Permethrin spray. Tonight we will treat again with the Udder Butter (we got an immense tub of it, lol). Since there is a two-week span between egg hatches, that should take care of the problem, but just to be sure we will probably treat in another two weeks just to be sure. If anyone feels this is not adequate, I would love to hear from them. We really want to be sure to get this under control, thanks!
