If you just wormed them recently you will need to worm them again with something like safeguard for goats it kills more of the worms that peafowl are susceptible to and those can cause problems if not taken care of, not sure how long you should wait to re worm them with ivermec as i never use that for worming my birds just use it for external parasites and i also use it as a heart worm preventive for my dogs.
Peas need to be wormed pretty often, when i just had chickens i hardly ever wormed them but once i got peas all that changed now everything on the place gets wormed cause my birds are free and everyone eats together, cost me a small fortune when the numbers get into the 100's
Can someone recommend the waiting period between these two wormers ivermec and safeguard for goats ???????
