I would like to have a solid worming routine for my flock as it seems waiting for the "signs" of infestation leads to too much stress on the girls. After reading many posts I have come to the conclusion that Valbazen and Safeguard will be my weapons of choice. If I start worming with Valbazen, do I then worm with Valbazen again in 10 days or then use safeguard and then 10 days later use Safeguard or Valbazen again? Do i use them one at a time, or together, or one after the other for the full 24 days X 2 . I would like to get the effectiveness offered by both products. My flock currently has worms. And should I keep the kids away from the birds and their free ranging area for the 24 days? do parasites/worms transfer to humans? Thank you all for your past help and shared knowledge!
