X2. Bang for the buck is Valbazen. It will treat the most worms with a small amount.
Safeguard is also good, but it requires a 5 days dose to be effective.
Ivermectin is not a very good poultry wormer. Lots of worms are resistant to it. I have studies if you want to read about it.
Strongid (pyrantel pamoate) won't treat as many worms as Valbazen or Safeguard.
Wazine only treats large roundworms.
If you want to deworm, get the Valbazen. One bottle is about $45 and will last a very long time.
