Actually you only need one product. You can get by with Ivermectin or febendazole either one for both the pig and the chickens. Chickens don't usually develop Cecal or capillary worms but if you have turkey or peafowl or maybe pheasant they do get these worms. So for the person with chickens and ducks but not other fowl, the ivermectin will get all the other worms the chickens will get. This also won't hurt ducks. I have ducks that get in treated chicken water in my building all the time and they do fine with it. Just be sure they don't spill and splash it all out. The advantage to the pigs and febendazole is that you can put it in water or feed rather than inject it. However pigs will dump the water and dig through the feed unless it is in controlled water or feed dispensers. So it's possible they won't get the right dose that way. And if you have several it could be a nightmare trying to figure out how much to use.Oh holy mother of all! I got lost! I got the dog stuff but lost it at pig stuff lmbo. I'm gonna have to sit down and think this out. Or maybe have my brainy daughter help.
So I only need two products for the worming of my chicken and pigs? Can my ducks drink the same water they all roam around the yard together. I can split them up if I need to. If I can get them all in one shot that would be awesome. The pigs worry me because they are jerks and won't sit still. I may have to get the squeeze shoot out. I have all my animals just running around together. Is that a bad thing? I'm wondering if they are passing worms around. And once I worm what do I do to kill the ones on the ground?
The questions never end. Maybe I'm over thinking!

I'd probably choose ivermectin for ease of use. Yeah if your pigs aren't very nice you'd probably have to use a shoot or a strong helper to give shots.
And no it's not bad for animals to run together. Most worms and internal parasites that infect one class and order won't infect another. So to be clearer worms that affect birds will not infect pigs. And worms that infect pigs will not infect humans. With the exception of a few like hookworm which would be killed by the dewormer. Every species can get round worm for instance but the round worm a dog, or chicken might have is not the same kind that could affect humans.
Again it's not bad for animals to run together and they can have a very symbiotic relationship to help each other out. But the key to it being successful is to keep your animals in good physical condition. Ridding them of worms and parasites is the first step in keeping them healthy. There is no way to keep the ground totally free of parasites. Good management of livestock can help, but they are brought in by earthworms and in wild bird poop.

I've never had one and never hope to. From what I've read I don't think their chances are good at all, because by the time they lay it they are already too infected.
