Yes.So the Safeguard for goats works for chickens? Is that the formula you recommend?
You can use Safeguard liquid goat dewormer or Safeguard Equine paste.
Dose is the same for either one of them:
0.23ml per pound of weight give orally once a day for 5 day in a row to treat most all worms chickens can have except for Tapeworms.
