I plan to dose my chicken flock with Wazine-17 wormer tomorrow. I found some roundworms in a chicken's poop & know I need to dose everyone. Do I need to dose the geese? I have a pair of Embdens who free-range all around the yard all day. They periodically come back to the area by the pens to eat & drink throughout the day. Should I keep them confined to their pen with Wazine-free water all day? They won't like it but I'd rather be safe than sorry.
