hi all! A while back I wormed my chickens, because they showed a few symptoms of having worms (they were underweight and had green poop), but they didn't regain all their weight. I've been feeding them extra, and adding corn and sunflower seeds to what I've been giving them, but they still aren't getting any more weight. All of them are getting lighter in weight, and their breastbones are very sharp. I'm really worried about them, I thought maybe I could worm them again since it's been quite a while since I wormed them last, but i'm not sure if that is the problem. Does anyone have any helpful info? It's very cold where I live as well.
