Hi! I'm interested to hear what people use when worming chickens. I haven't worked ours yet as haven't had long and they weren't planned!! They found us. So do I treat the chickens with anything even if they don't have worms? I read it's a 6 monthly thing but I'm unsure of what products to use. I have two hens and would appreciate some advice. they are around 5 months of age. Many thanks .
