Cheap chicken food often means inferior quality ingredients, and can be a false economy. With creative marketing on the outside of the bag, it’s hard to assess the ingredients in poultry feed. You may not notice problems until after several months. I find the hatchability of eggs and the health of chicks is a good indicator of the quality of nutrition your hens are receiving. Feeds that include grit are cheaper. Keep in mind the weight of the grit is included in the cost, and your hens will need to eat more of this feed to meet their energy requirements. It can be challenging to make a price comparison with standard feeds. I prefer to feed grit separately, and my hens can take what they need.
