Hi all - I read in some recent posts that pumpkin seeds and buttermilk can act as a natural de-wormer. Has anyone done this effectively? We've got a small flock of 9, all of whom are all less than six months old. I'm not comfortable worming them yet, but I've seen some suspicious stools in the hen house the last few days, and I'd like to try something. Any advice would be much appreciated. PS - none of the pullets are laying yet, if that matters to anyone's analysis. Thanks!
