I have 14 in my flock. When I got the original 4 they had some red mites on them. I dusted them and thought they went away. Then, got more chickens. Today when I picked up one of my little ones and was scratching around on him and lifting his feathers, I saw those little suckers running around. If they're on him, they're on them all for sure. I'm going to completely clean out my coop (which is only like 2.5 months old) and put new bedding in there. Should I bathe them AND dust them, or if I dust every few days will that be fine? I just want to take care of this once and for all.
