One of my 2 yr. old hens has I think taken over since the rooster died. There are 8 hens in all, 3 two year olds, and 5 one year olds. The bossy one, Skittles, walks around complaining when I go outside. She runs to me, complaining all the while, follows me around. They have plenty of food available and free range all day. I dusted them last week for mites, and I will follow up in a few days with Eprinex when it gets here, to 2nd dose them for mites, and catch any worms they might have. I'm thinking she doesn't feel well, maybe she does have worms and we'll see if the Eprinex helps her, but -- does one hen just get bossy and push everyone else around and complain all the time?
