One of my chickens has worms. So I called around the nearest farm store, and some pet stores. Got the answer - "We didn't know chickens could get worms". Then I drove 35 miles to the only decent farm store around here. The clerk recommended Wazine 17. In fact it was the only thing they had that was specifically for poultry. So I will put it in their water in the morning. Now, how many days do we have to wait till we can eat their eggs again? Also, do I really need to give this Wazine every 30 days? If that's the case I guess I'll never get to eat the eggs again.
