You can use use Safeguard or Panacur (fenbendazole 10%) on them. I use the liquid at 50mg/kg (0.5cc/ml per 2.2 pounds) by mouth and repeat in ten days, but you can use the paste, too, exact same amount. Do not let the fees store sell you Wazine, it only gets roundworms! While you're at it, dust them for mites and lice even if you cannot see any.I haven't, what would you suggest? I have a feed store close by I can run to and pick something up. What is the dosage, and do you administer to each bird individually or...? I guess I worm my horses and dogs routinely I just didn't think to do the chickens too.
