Ok- so many things i have learned and keep learning. After a few things have happened in this process the Tractor supply place told me to use Wazine on my flock every 30 days. ok so now i worried about my dog and a puppy that frequents our yard (of course they eat the chicken poop). The owner was taking her puppy to the vet for puppy stuff i asked her to ask about the chicken poop and if it was harmfull. Vet found hookworms in the puppies stool! the Wazine does not state it treats hook worms, vet says it most likely came from chickens, so now how do i know and how do i treat chickens and my dog?
