My chickens have recently developed what I call "mud butt". Where their poop is runny and leaves a trail on their down feathers when they poop. I've only had birds for one year. I have been using DE for worming but I noticed my new rooster I've had for 4 months started stretching his neck and shaking his head, laying down in the yard, staggering when he got up. I caught him yesterday and examined him visually and couldn't find anything. He acted normal other than the symptoms I described above even topping hens off normally. I went to feed this morning and he was dead in the run. I researched online and found his symptoms line up with worm infestation. So I went and bought Safe Gaurd pellets and gave with feed today. I'm noticing alot of people using Wazine 17. I was thinking wait 10 days and treat with the Wazine? Any advice would be helpful. Also I've started some of my hens in a seperate coop to lay out and hatch off his fertilized eggs while I still can. In an attempted to hatch off a new rooster. Any reason why I shouldn't hatch chicks while worming.
