Yes. Just in two ladies I bought a few days ago...which I now believe is appropriate to say I rescued (long story)...though I don't know enough about worms to say what they were. It just made me start to wonder what others use. I did one round treating for roundworm cuz that's all my feed store had for chickens, but I'm thinking I need to follow up with Safeguard or something as I did some reading on here and that is one that I understand kills additional types. ??!
Safeguard or Valbazen are good wormers.
