I buy organic feed from AR (Agri Rijnvallei) together with my friend. Its cheaper, fresher and has more protein than Welkoop. But you can only buy if you are willing to take at least 100kg. PM me if you want more details.I want to change over into all flock but that one is I think around 16% protein, while layer feed is 14.4%. The highest protein chicken feed I have found so far was 19.1% chick crumble. Although this was all in the Welkoop shop, so maybe I need to change shops.
