Last week a used Rooster Booster wormer to worm my birds. I hadn't seen any worms but just did it as a precaution. I was cleaning the poop board yesterday and saw lots of worms in the poop. Shouldn't the wormer have killed them? I went to the feed store today and got Strike III type B wormer as the Wazine didn't have a withhold time, just said not to use on birds that lay for human consumption. So I guess my question is does the wormer kill the worms or just make them be pooped out?
