On Saturday, I treated my little backyard flock with Wazine in their water. None of them were showing any symptoms, but I'd been reading that it is good to worm once a year or so. My question is, since Wazine is just for roundworm, do I need to follow up with a different medication in two weeks? If so, what should I get. My TSC had some wormers for dogs, cattle, pigs, etc...but I get nervous buying those when I don't know which one is best for chickens or how to scale the dose for chickens.
