So I currently have one of my hens separated because my rooster has taken a liking to her and she has no feathers left on her head. I just went out to the garage and niticed she crapped on my motorcycle. There was a long red worm almost like an earth worm. She is the fattest hen in my flock which I find odd. Also I just scraped my poop board with 4+ days of poop and didn't notice any worms whatsoever. Is it possible for just one hen to get worms? Does this long red worm sound like a problem? Do I need to de worm the hen in question? The whole flock? The goats? The dogs?? Thanks!
