I've not see that type, although it is safeguard. I used the goat wormer. But the main ingredient is the same as the dog stuff. The problem with the dog stuff is that it's something you put in their food and suggests wet food, so I don't know that it'd work with chicken feed. The goat wormer can be put in their drinking water..
