-recently had one hen with tapeworm (as apparent from the segments shed in the droppings). -treated with Verm-x, and have seen a significant difference. -only a few segments in her droppings after several days of treatment. Yesterday, I found nothing. I scoop the coop, daily, and the lawn and run multiple times per day. -seems to work. -that being said, if I see any signs to the contrary I won't hesitate to order some Valbazen. My hen looks healthy, is laying daily, and is very active. She seems fine. -BUT, if segments return to the droppings, she'll be treated to eliminate the issue. -don't intend to lose a hen to somehing that is treatable. (I always preference natural, first, but will do what's necessary to preserve my flock.)
