Quote:Commercial operations have layers on wire for about 2 years before they are replaced. No worm problems there. If worming defeats the purpose of you raising chickens, that you dont want to do, that is your choice. But if you want healthy chickens and healthy eggs, and they are not free ranging and you only have them in a pen with dirt under their feet...they will get worms eventually. The oocysts are in the soil and will be picked up by your chickens. Worms cause weakness, weakness opens the door to diseases. Kill the worms and their immune system deters disease.
