Hi all, I found small,short, white LIVE moving worms that I think are tapeworms on some of the chicken droppings of my free ranging hens. Need advice on what to treat with...Ivermectin?? Egg production has been on the decline for awhile now, so I suspect this has been going on for some time. All my chickens are at least 4 months old ranging up to 1 1/2 yrs old. I would like to treat ASAP. I also have dogs that eat the droppings of the chickens --- I know, SOOOO gross--- will need to worm them too I suppose?
