I don't think it matters if it is packaged as goat or horse wormer - the only important factor is the active ingredient: Fenbendazole. (Panacur horse wormer also has the active ingredient Fenbendazole so could be used interchangeably.) When I was doing my research, Fenbendazole was one of the recommended treatments for capillary worms. I don't know for sure if he has those or not, but figured if he is a little down only a month after Ivermectin treatment, it is best to try something with a different active ingredient. And, since he is the only one I want to treat, it doesn't make sense to me to do something that goes in the water or feed and treat the whole flock. So, I think probably the paste is my best bet, since I can administer it just to him. I think I will follow the package directions and do the second treatment after 10 days, and hopefully that will knock out any that have hatched since the first treatment.
I know I was the one who originally suggested the Ivermectin in the water worm treatment but this time of year I don't favor the treatments that have to be administered via the water. If I use my gravity waterer, it freezes, but if I use a heated water bowl, the ducks splash it out and waste it. So - at this time of year I am looking for ways of administration that are more direct. I don't want to put a bird in a separate pen to try to dose via the water or feed, when the temps are going to be in the negatives during the time frame of the treatment.
I did the Ivermectin about a month ago during a period of days when the temp was staying above freezing even at night (I can barely remember what that is like now!) and I got lucky that by the time they needed the second dose 10 days later, it was still mild. I wanted to dose at a time of year when they weren't producing many eggs but it is also real iffy this time of year when you don't want the medicated water freezing. Sigh. At least with a tom turkey I don't have to worry about withdrawal on either eggs or meat, but its another reason not to treat the whole flock right now, since egg production is really good and I don't want to have to discard a couple dozen eggs a day.

Somehow, I can't imagine you being a burden when you visit. It sounds to me like you're always busy doing something productive, and I can only imagine that you'd be super helpful when you visit your grandkids.
