Like enola just said ( two coments down) it's better to keep healthy flock by their own. Culling weak chickens is a good start.yeah? That's what I used to think, too. Check it out on here and you'll see how many people do deworm regularly as a matter of course. There are dewormers you can use where you don't have to stop eating the eggs, as well as Corid, you can eat the eggs while they are on it. If one has Cocci, they are all going to have it. Some may not show symptoms. We had a severe problem with Capillary worms last spring....we lost several of our nice birds because they never showed symptoms until it was too late. That's when I learned the good reasons behind deworming regularly. If you're not going to deworm, at least have random fecal checks every six months.
