Chickens love to eat vegetable scraps and other kitchen leftovers, so add variety to their diet and reduce your bill from the feed store at the same time.
Much of the initial outlay when setting up a new coop and run can be reduced by building your own with materials you might already have or can find cheaply.
Bulk purchases are usually cheaper per pound, so consider buying larger quantities if you have a suitable place to store them.
Grow some of your own feed, such as oats, sunflower seeds, or comfrey, to further cut feed costs.
If you have a large yard or space for chickens to roam, allowing them to free-range can help supplement their diet with grasses, insects, and other natural food sources.
Use salvaged wood, old pallets, fencing, or even discarded furniture to build or reinforce your chicken setup.
