Buy economically and get enough feed, grit, sunflower seeds and straw to last you for ages. The True Value Pack will last over 3 months for 2 chickens and over 2 months for 4 chickens based on each chicken eating 100g of mash per day. The grit will help with digestion and adds calcium to make the eggs and the sunflower seeds will help make the yolks a golden orange colour when adding a very small handful every 2 or so days. 

This is True Value.
