We have several black walnuts on our property that drop lots of yummy nuts each year. I want to make my walnut stain for the chicken pen and patio furniture and make a natural pet wormer too. How much walnut powder per chicken should I administer? I searched and only found one post mentioning dosage. I'd just like to confirm it before I order some powder. The nuts aren't formed on my trees yet but I would like to go ahead and worm the chooks now. Thanks guys!
