Hi, I am after a cheaper alternative to having poultry for feed and I can buy wheat and / or barley at a very cheap price per ton. I was wondering if I could give it to my pekin ducks, muscovy ducks, saxony ducks and sussex chickens as their only diet from my. I would give them probably about 100 grams per chicken and 200 grams per duck or something around there. They are able to free range over 20 acres with lots of bugs and grasses for them to eat and was wondering if that would finish of their diet at least for autumn, spring and summer. I may add mealworms or regular worms to their diet especially during the winter months when the bugs are nearly no existent. Thanks for the help.
