For the past six years, I have fed Poulin grains for my horses and now for my chickens and ducks. The pellet has the following nutritional values, however, my birds do not seem to be gaining and keeping weight on. Guaranteed Analysis Crude Protein (Min) 15.00% Lysine (Min) 0.70% Methionine (Min) 0.30% Crude Fat (Min) 3.00% Crude Fiber (Max) 4.00% Calcium (Min) 3.50% Calcium (Max) 4.50% Phosphorus (Min) 0.60% Salt (Min) 0.25% Salt (Max) 0.35% As they are not free range the girls get scratch feed, 32 oz. per 17 hens (SLW,GLW, BR, BO, BA's - so heavier breed standards) daily, fresh water, oyster shells, weed pullings and veggie treats. Oh and grammy likes to give them bread squares. I will contact my Poulin rep tomorrow, but if anyone sees something blatantly wrong with their diet, please comment. Thanks.
